OPINION
AGEE, Circuit Judge:
John Alvin Roe was convicted of one count of impersonat-
ing an officer or employee of the United States, in violation
of 18 U.S.C. § 912. On appeal, Roe contends the district court
erred in the admission of certain testimony, in determining the
sufficiency of the evidence, and in the giving of one instruc-
tion to the jury. Finding no error, we affirm the judgment of
the district court.
I.
In April 2008, a federal grand jury returned an indictment
charging Roe with one count of violating 18 U.S.C. § 912 by
"hold[ing] himself out to be a federal police officer and [iden-
tifying] himself as a federal police officer."1 (J.A. 9.) Roe pled
not guilty and proceeded to a jury trial.
Viewed in the light most favorable to the Government,
United States v. Seidman, 156 F.3d 542, 547 (4th Cir. 1998),
the evidence adduced at trial showed the following: In the
1
The indictment also charged Roe with one count of possession of a
false badge of an agency of the United States, in violation of 18 U.S.C.
§ 701. The district court subsequently granted Roe’s motion for judgment
of acquittal as to that count. Because jeopardy had long since attached by
the time the district court did so, United States v. Siegel, 536 F.3d 306,
315 (4th Cir. 2008), the Government was statutorily prohibited from pur-
suing an appeal of that decision. See 18 U.S.C. § 3731.
UNITED STATES v. ROE 3
early morning of November 9, 2007, Maryland State Police
Corporal Terry Allen drove in an unmarked vehicle on the
Baltimore-Washington Parkway ("Parkway"). Corporal Allen
observed a Ford Crown Victoria "package" travelling in the
left lane. Corporal Allen explained that by "package" he
meant that the Ford bore certain indicators of an unmarked
police vehicle, including emergency lights in the rear window,
antennae, and a plain white body. When Corporal Allen first
attempted to pass the Ford, the Ford’s driver, later identified
as Roe, "cut his interior lights on" and stared at Allen for
"several seconds." (J.A. 35.) Corporal Allen testified he
"thought [Roe] was going to pull [him] over, so [he] stayed
slightly behind" the Ford instead of passing it. (J.A. 35.)
As the vehicles proceeded on the Parkway, Corporal Allen
decided to telephone the United States Park Police ("Park
Police") because the vehicles were approaching the jurisdic-
tional line for the Maryland State Police and the Park Police.
Allen had become suspicious that Roe was impersonating a
police officer based on Roe’s attire and conduct. During the
course of the telephone call, Corporal Allen once more
attempted to pass the Ford, at which time Roe activated his
vehicle’s siren. Upon hearing the siren, Corporal Allen
"backed off." (J.A. 44.) A short time later, he again tried to
pass the Ford, and upon doing so, heard Roe using the vehi-
cle’s loudspeaker to order him to slow down. Corporal Allen
remained on the telephone with the dispatcher, who informed
him that a Park Police unit was en route. Corporal Allen testi-
fied that as the vehicles came upon an interchange, the Ford
"pulled in behind [him and] activated the actual [red and blue]
emergency lights" "in the high windshield" of the Ford. (J.A.
46.) Believing the Ford "was actually going to pull [him]
over," Corporal Allen "proceeded over to the shoulder" just
past an exit ramp. (J.A. 46-47.) As he pulled over, the Ford
took the ramp off the Parkway.
Corporal Allen testified that as he slowed along the shoul-
der, he noticed a Park Police vehicle follow the Ford onto the
4 UNITED STATES v. ROE
ramp. He decided to back up his vehicle onto the ramp in
order to provide the Park Police officer support.
United States Park Police Officer Adam Zielinski followed
Roe off the Parkway ramp and initiated a traffic stop. Both
Roe and Zielinski exited their respective vehicles. Roe was
wearing a tactical police vest, black cargo pants, and a hand-
gun in a holster. Zielinski pointed his service weapon at Roe
and ordered him to stop moving and show his hands. Instead
of obeying Zielinski, Roe continued "advancing on" Zielinski,
saying, "I’m the police, I’m the police," and informing Zielin-
ski he was a federal police officer. (J.A. 79.) Roe continued
advancing, despite Zielinski’s repeated command to stop. The
third time Zielinski told him to stop, Roe obeyed, and then
removed his wallet and showed Zielinski a gold badge with
red and blue markings, containing a seal in its middle, the let-
ters "N-A-S-A," and the word "police" on it. Zielinski, who
was familiar with the security badges issued by the National
Aeronautics and Space Administration ("NASA"), recognized
Roe’s badge as a fake. Zielinski holstered his weapon and
placed Roe in handcuffs. He asked Roe where he got the
badge, and Roe replied that he had the badge made. Officer
Zielinski testified that during this encounter, he overheard a
scanner from inside Roe’s vehicle; the scanner was tuned to
the Park Police frequency, as Zielinski recognized his dis-
patcher’s voice speaking on it. Officer Zielinski subsequently
retrieved, inter alia, a Maryland handgun permit and Mary-
land private detective and security guard certifications from
Roe’s wallet.
Thomas Evans, acting chief of security for NASA’s God-
dard Space Flight Center, testified that the private company
Sec Tek provided a contract security force for the Goddard
Campus in Greenbelt, Maryland. While NASA has no police
department of its own, it relies on Sec Tek to provide two
types of security officers: a "basic security officer," who may
be armed, and a "security police officer," who has "federal
arrest authority."
UNITED STATES v. ROE 5
Evans stated that Roe worked for Sec Tek as a "security
officer at Goddard" who had "federal arrest authority" "on
Goddard Space Flight Center property."2 (J.A. 115, 118, 123.)
Evans testified that patrolling roadways "off of" the Goddard
campus would not be an assignment for Roe, and that making
traffic stops on the Parkway was outside Roe’s responsibility.
He further testified that although Sec Tek security police offi-
cers have arrest authority on Goddard property "if necessary
and under exigent circumstances," to his knowledge they had
never used such authority. (J.A. 118.)
Over Roe’s objection, Sergeant James Russell, with the
Maryland State Police Licensing Division, testified concern-
ing items recovered from Roe’s wallet. According to Russell,
the Licensing Division regulates handgun permits as well as
security guards and private detectives in Maryland. Sergeant
Russell testified that private detective and security guard cer-
tifications did not provide a person with arrest authority or
constitute the holder a police officer. He also testified that a
handgun permit did not authorize the holder to make arrests.
At the close of the Government’s evidence, Roe moved for
a judgment of acquittal, contending that the Government had
not satisfied its burden of proving Roe falsely held himself
out to be a federal officer and identified himself as such
because Roe was a federal officer and there was no evidence
that he had acted as a federal police officer. The district court
denied Roe’s motion.
In instructing the jury on the elements of the offense, the
district court initially stated as follows:
[T]here is a single charge that you will consider in
2
Roe also held a credential issued by NASA’s Federal Enforcement
Training Academy that allowed him to carry firearms and make warrant-
less arrests on NASA property, in accordance with 42 U.S.C. §§ 2456 and
2456a.
6 UNITED STATES v. ROE
the case and that is the charge of false personation in
violation of 18 United States Code, Section 912. And
the indictment in this case, which again[,] is a mere
accusation, charges that on or about November 9,
2007, in the District of Maryland, the defendant John
Alvin Roe did knowingly and unlawfully falsely
assume and presume to be an officer employee and
employee [sic] acting under the authority of the
United States and that he did act as such. That is,
that he held himself out to be a federal police officer
and identified himself as a federal police officer.
(J.A. 203.) The court continued:
Now, here are the elements of that alleged offense.
To find [Roe] guilty of this crime, the [G]overnment
would have to prove beyond a reasonable doubt each
of the following elements. First, that [Roe] was not
an officer or employee of the United States at the
time in question. In this case, not a police officer.
(J.A. 203.) In a bench conference following all of the jury
instructions, the Government requested that the court reissue
an instruction to correct its prior use of the word "presume"
rather than the word "pretend." The district court then issued
the following instruction:
Now . . . what I’m about to tell you now is not to sin-
gle out an instruction. It’s just to correct a possible
. . . in this case, alleged misspeaking. I want to read
to you what the statute says that [Roe] is charged
within this case . . . .
The statute reads, quote, whoever falsely assumes
or pretends to be a police officer or employee acting
under the authority of the United States or any
department, agency or officer thereof, and acts as
such is guilty of an offense.
UNITED STATES v. ROE 7
And that essentially is what is alleged in the
indictment. First, I read to you the statute and the
indictment alleges that [Roe] did knowingly and
unlawfully falsely assume and pretend. If I said the
word presume, that’s incorrect. The word is pretend
....
(J.A. 209-10.)
The jury found Roe guilty. At sentencing, Roe moved for
a new trial pursuant to Federal Rule of Criminal Procedure
33. The district court denied the motion. The court sentenced
Roe to twelve months’ probation, with the conditions that he
spend four months in a community corrections facility and
four months on home detention.
Roe noted a timely appeal, J.A. 233, and we have jurisdic-
tion pursuant to 28 U.S.C. § 1291.
II.
Roe contends on appeal that the district court made the fol-
lowing errors, which require his conviction be reversed:
allowing the admission of Sergeant Russell’s testimony, find-
ing the evidence sufficient to convict, and giving the jury
instruction regarding impersonating a federal police officer.
We address each argument in turn.
A.
First, Roe contends the district court abused its discretion
in allowing Sergeant Russell to testify about the authority
possessed by the holders of a Maryland private detective and
security guard certification and a handgun permit. Roe asserts
that Sergeant Russell’s testimony constituted "expert" testi-
mony, and that the district court abused its discretion in
admitting it even though Sergeant Russell had not been desig-
nated as an expert witness prior to trial (Fed. R. Cr. Pro.
8 UNITED STATES v. ROE
16(a)(1)(G)), nor been qualified as one at trial (Fed. R. Evid.
702). Moreover, he maintains that the court’s error was not
harmless because Sergeant Russell’s testimony was necessary
for the jury to determine that Roe did not have lawful author-
ity to effectuate a traffic stop on the parkway.
We review the district court’s admission of testimony for
abuse of discretion. United States v. Lancaster, 96 F.3d 734,
744 (4th Cir. 1996) (en banc). Such discretion is abused only
when a "district court act[s] arbitrarily or irrationally." United
States v. Moore, 27 F.3d 969, 974 (4th Cir. 1994) (internal
quotation marks omitted). Evidentiary rulings based on erro-
neous legal conclusions are "by definition an abuse of discre-
tion." United States v. Turner, 198 F.3d 425, 430 (4th Cir.
1999). Evidentiary rulings are also subject to harmless error
analysis. United States v. Brooks, 111 F.3d 365, 371 (4th Cir.
1997).
A lay witness may testify "in the form of opinions or infer-
ences" that are "(a) rationally based on the perception of the
witness, (b) helpful to a clear understanding of the witness’
testimony or the determination of a fact in issue, and (c) not
based on scientific, technical, or other specialized knowledge
within the scope of Rule 702." Fed. R. Evid. 701. Where "sci-
entific, technical, or other specialized knowledge will assist
the trier of fact to understand the evidence or to determine a
fact in issue, a witness qualified as an expert by knowledge,
skill, experience, training, or education, may testify thereto in
the form of an opinion or otherwise" when certain conditions
are met. Fed. R. Evid. 702. We have previously recognized
that the distinction between lay and expert testimony "is a fine
one" and "not easy to draw." United States v. Perkins, 470
F.3d 150, 155 (4th Cir. 2006) (internal quotation marks omit-
ted). In describing this tension, we have observed:
While we have noted that a critical distinction
between Rule 701 and Rule 702 testimony is that an
expert witness must possess some specialized knowl-
UNITED STATES v. ROE 9
edge or skill or education that is not in possession of
the jurors, we also have acknowledged that the sub-
ject matter of Rule 702 testimony need not be arcane
or even especially difficult to comprehend. The
interpretive waters are muddier still: while lay opin-
ion testimony must be based on personal knowledge,
expert opinions may also be based on first hand
observation and experience.
Id. at 155-56 (internal quotation marks and citations omitted).
Having reviewed Sergeant Russell’s testimony, we con-
clude the district court did not err in admitting it as lay testi-
mony. Sergeant Russell was in charge of the unit that issues
handgun carry permits, as well as security guard and private
detective certifications in Maryland. He was qualified to tes-
tify as to the requirements for getting such permits and certifi-
cations and to state what possessing those permits permitted
an individual to do based on his personal knowledge acquired
in that capacity. See MCI Telecommunications Corp. v. Wan-
zer, 897 F.2d 703, 706 (4th Cir. 1990) (holding a bookkeep-
er’s "testifying on the basis of records kept by her personally
under her control, and her projection of profits under the lease
as prepared by her was predicated on the personal knowledge
and perception" and as such constituted lay testimony whose
identification as an expert witness was not required). Such
knowledge was not "specialized knowledge" in the Rule 702
sense, and does not constitute expert testimony. Instead, it
falls under Rule 701’s description of lay testimony, being "ra-
tionally based on the perception of the witness" and helpful
to the jury’s "determination of a fact in issue." Accordingly,
Roe’s challenge to the admission of this testimony lacks
merit.
B.
Roe also contends the district court erred in finding the evi-
dence sufficient to convict him of impersonating a federal
10 UNITED STATES v. ROE
officer. We review challenges to the sufficiency of the evi-
dence de novo. United States v. Kelly, 510 F.3d 433, 440 (4th
Cir. 2007). "In doing so, our role is limited to considering
whether there is substantial evidence, taking the view most
favorable to the Government, to support the conviction." Id.
(internal quotation marks omitted). "[S]ubstantial evidence is
evidence that a reasonable finder of fact could accept as ade-
quate and sufficient to support a conclusion of a defendant’s
guilt beyond a reasonable doubt." United States v. Burgos, 94
F.3d 849, 862 (4th Cir. 1996) (en banc). If there is substantial
evidence to support the guilty verdict, then we must sustain
the verdict. We do not reweigh the evidence or the credibility
of witnesses, but assume that the jury resolved all contradic-
tions in the testimony in favor of the Government. Kelly, 510
F.3d at 440; see also United States v. Moye, 454 F.3d 390,
394 (4th Cir. 2006) (en banc).
18 U.S.C. § 912 states, in relevant part: "Whoever falsely
assumes or pretends to be an officer or employee acting under
the authority of the United States or any department, agency
or officer thereof, and acts as such . . . shall be fined . . . or
imprisoned not more than three years, or both." In United
States v. Parker, 699 F.2d 177 (4th Cir. 1983), we stated that
"[t]wo distinct elements comprise the crime with which [the
defendant] is charged: 1) [the defendant] must have falsely
assumed or pretended to have been a federal agent, and 2) he
must have acted as such." Id. at 178. Roe challenges the suffi-
ciency of the Government’s evidence as to each element.
Regarding the first element, Roe contends that he "could
not have pretended to be a federal officer" because the record
showed that he was a federal officer, employed as a "security
police officer" with arrest authority on NASA property.
(Appellant’s Br. 23-24, 27.) However, Roe incorrectly reads
§ 912 to mean that an individual cannot, as a matter of law,
be convicted of impersonating a particular kind of federal
officer or employee if the individual is any kind of federal
UNITED STATES v. ROE 11
officer or employee. The district court aptly observed the
problem with Roe’s argument:
[T]hat’s a bit of a fine spun distinction. The question
is, he could be a federal officer and be someone who
inspects poultry . . . but the issue here, was he a fed-
eral police officer; that’s what the case is about. Not
whether he was a federal officer in some respect, and
maybe even he was somewhat close to a police offi-
cer, but the mere fact of being a federal officer
would not be the answer, it’s being a particular kind
of federal officer.
(J.A. 155.) The prohibition in § 912 is on impersonating the
officer or employee that the person is not, regardless of what
the person’s actual position may be.
The Ninth Circuit Court of Appeals also recognized this
point in Russell v. United States, 271 F. 684 (9th Cir. 1921)
(applying a predecessor statute to § 912). There, a timber
inspector employed by the United States Navy Department
was charged with impersonating a United States revenue offi-
cer. Id. at 684-85. The defendant maintained that "inasmuch
as [he] was in fact an officer employed by the [Navy], he
could not be held guilty of the offense of assuming or pre-
tending to be an officer and employ[ee] acting under the
authority of the United States." Id. at 685. The Ninth Circuit
rejected that argument, holding "[i]t is no defense to him that
he was employed in some other department of the govern-
ment. There can be no question but that an employ[ee] of one
department of the government may be held guilty of falsely
impersonating an officer of another department." Id.
Similarly, here, there was ample evidence in the record for
the jury to conclude that Roe was not a federal officer, and
specifically not the type of federal officer he purported to be
when the events with Corporal Allen unfolded. Roe’s
employer was a civilian company, Sec Tek, and through that
12 UNITED STATES v. ROE
entity, Roe was a contract security guard at the NASA God-
dard facility. Roe’s assignment as a security officer extended
only to NASA’s Goddard property, and not to the Parkway
where the incidents in question unfolded or to any other fed-
eral property. Similarly, the federal arrest authority Roe pos-
sessed as part of his employment was limited to emergencies
occurring on the Goddard property. Yet Officer Zielinski tes-
tified that Roe told him, "I’m the police, I’m the police" and
that he was "a federal police officer." On this record, suffi-
cient evidence supports the jury’s conclusion that Roe
claimed to be a federal police officer when in fact he was not.
Roe also asserts the Government failed to prove the second
element of the offense, that he "acted as" a federal officer.
Roe’s initial argument is two-fold: first, he claims that the
jury was only permitted to consider the evidence of Roe’s
interaction with Officer Zielinski in determining his guilt; sec-
ond, he contends that the interaction with Zielinski was insuf-
ficient to satisfy this element of the offense. In the alternative,
Roe asserts that even taking into consideration his actions
toward Corporal Allen, nothing he did "asserted any federal
authority." (Appellant’s Br. 28.)
Roe contends the district court instructed the jury to limit
their consideration of his conduct to his interactions with
Officer Zielinski, and that the jury could not consider any of
his conduct with Corporal Allen when determining whether
he acted as a federal police officer. The limiting instructions
Roe relies on were given during Corporal Allen and Officer
Zielinski’s testimony, and limited the jury’s consideration of
their respective conversations with the Park Police dispatcher.
The court instructed the jury that "what the dispatcher says is
not offered for the truth of the matter, it just explains to you
how they got where they got." (J.A. 43.) The court did not
otherwise limit the testimony of either Corporal Allen or Offi-
cer Zielinski in describing the events of November 9, 2007.
The limiting instructions were not broad prohibitions as to
UNITED STATES v. ROE 13
considering Roe’s conduct toward Corporal Allen as evidence
of Roe’s guilt, that is, in acting as a federal officer.
This understanding is consistent with other portions of the
trial record, which show that the Government prosecuted the
case — and Roe defended it — based on Roe’s entire course
of conduct with both Corporal Allen and Officer Zielinski.
For example, Roe’s motion for judgment of acquittal chal-
lenged the sufficiency of the evidence as to either encounter
(with Corporal Allen or Officer Zielinski) to support a guilty
verdict. Similarly, under the Government’s theory of the case
encapsulated in its closing argument, Roe was "trying to make
a traffic stop" on the Parkway, and falsely asserted to be a
federal police officer in order to justify his actions to Officer
Zielinski. As support for this theory, the Government’s clos-
ing argument frequently referred to Roe "acting as a police
officer" as it described Roe activating his vehicle’s lights and
siren toward, and speaking on the loudspeaker to, Corporal
Allen while the men were driving on the Parkway. Defense
counsel’s closing argument also recounted the entirety of the
events that day, breaking down and attempting to discredit
Corporal Allen’s testimony regarding Roe’s conduct, and
pointing to the fact that Roe never effectuated a pull-over in
order to cast doubt on the Government’s interpretation of
Roe’s actions. At no point during arguments regarding the
motion for a judgment of acquittal or closing argument did
Roe contend that evidence of his interaction with Corporal
Allen could not be used to determine his guilt. The record
simply does not support Roe’s contention that the district
court limited the jury’s consideration of the evidence to Roe’s
interaction with Officer Zielinski.
Examining the entire record, we conclude sufficient evi-
dence supports the jury’s conclusion that Roe "acted as" a
federal police officer. In Parker, we held that the element of
"act[ing] as such" requires more than a mere representation of
being a federal officer or employee. 699 F.2d at 179. In Par-
ker, the defendant satisfied this element by asserting false
14 UNITED STATES v. ROE
authority over another individual when he claimed that "he
was investigating a report that [the third party] was not paying
taxes on the sale of firewood." Id. at 179. There, we cited with
approval a Fifth Circuit case where "the defendant falsely pre-
tended to be a federal officer and acted as such by signing the
register at a federal penitentiary as the associate attorney gen-
eral and representing to an inmate that he was the associate
attorney general." Id. at 180 (citing United States v. Cohen,
631 F.2d 1223 (5th Cir. 1980)); see also United States v. Mar-
tindale, 790 F.2d 1129, 1135 (4th Cir. 1986) (upholding § 912
conviction where defendant falsely claimed to be a U.S. State
Department employee, presented a fraudulent diplomatic
passport, and requested rental car discount from a Hertz Rent-
A-Car agent). We noted that "[a]lthough the defendant solic-
ited nothing from prison personnel or inmates, his representa-
tions . . . constitute[d] acts asserting his pretended authority."
699 F.2d at 180. And in our discussion of the element in Par-
ker, we observed "the government need only show that Parker
asserted his pretended authority over Brooks in some fashion
. . . . By demonstrating that Parker asserted the authority to
investigate [the third party’s] tax status, the government has
met its burden." Id.
Here, sufficient evidence supports the jury’s conclusion
that Roe "acted as" a federal police officer in a single chain
of unbroken events that began with Corporal Allen and ended
with Officer Zielinski. Roe engaged in actions that sought to
assert the authority of a federal police officer and which
"backed up" his statement to Officer Zielinski that he was a
federal police officer. Corporal Allen’s uncontested testimony
was that while he and Roe were driving on the Parkway, Roe
asserted police authority that he did not possess by instructing
Allen to slow down, activating his siren, and maneuvering
directly behind Allen while activating his vehicle’s red and
blue emergency lights. As a result of this conduct, the jury
could reasonably infer that Roe was initiating a police stop,
as Corporal Allen also testified he believed was the case. Both
Corporal Allen and Officer Zielinski testified without contra-
UNITED STATES v. ROE 15
diction that Corporal Allen was pulling over just past an exit
ramp, as Officer Zielinski’s marked Park Police vehicle came
into view. The jury could also reasonably infer that the reason
Roe did not effectuate the stop and proceeded onto the exit
ramp was that he knew Officer Zielinski was rapidly
approaching him because Roe was monitoring the Park Police
frequency on the scanner in his vehicle and saw Zielinski’s
marked Park Police vehicle.
Officer Zielinski then proceeded to pull Roe over, at which
point Roe exited his vehicle, repeatedly asserted he was "a
police officer" — and specifically that he was a "federal
police officer." Rather than obeying Zielinski’s instructions to
stop, Roe advanced on Zielinski — who at that point had
drawn his service weapon — and reiterated that he was a fed-
eral police officer. When Roe finally did stop, he voluntarily
showed Officer Zielinski a "NASA police" badge the he had
designed and had made in order to prove his assertion. These
actions demonstrate that Roe’s conduct exceeded a mere
claim of being a federal officer. By asserting the authority of
the officer he claimed to be to Officer Zielinski in his actions
moments earlier with Corporal Allen, Roe satisfied the statu-
tory requirement of "act[ing] as such", as discussed in Parker.
Roe also seems to claim that he could not, as a matter of
law, be guilty of violating § 912 since — at most — his
actions satisfying each element of the offense were directed
at different individuals. Nothing in § 912 requires such a nar-
row reading of the prohibited conduct. Furthermore, as noted
earlier, a continuous chain of events links Roe’s conduct
toward Corporal Allen and Officer Zielinski. There was no
break in time or action between Roe’s behavior toward Cor-
poral Allen and his statements and actions toward Officer
Zielinski. Accordingly, Roe’s conduct formed a single, com-
plete violation of both elements of § 912. For all of these rea-
sons, substantial evidence supports Roe’s conviction, and the
district court did not err in so finding.
16 UNITED STATES v. ROE
C.
Lastly, Roe asserts the district court erred in instructing the
jury that 18 U.S.C. § 912 proscribed the act of pretending to
be "a police officer or employee acting under the authority of
the United States." Roe contends the addition of the word
"police" in the oral instruction effectively charged the jury
with elements of a crime that does not exist, and construc-
tively amended the indictment. And he maintains that the mis-
reading of § 912 fundamentally changed the purported
violation so that the jury could convict him of pretending to
be a "federal police officer" even though there was evidence
that could have led them to conclude he was not guilty of the
actual offense, namely, pretending to a "federal officer."
A constructive amendment to an indictment occurs when
"the indictment is altered to change the elements of the
offense charged, such that the defendant is actually convicted
of a crime other than that charged in the indictment." United
States v. Malloy, 568 F.3d 166, 177-78 (4th Cir. 2009) (quot-
ing United States v. Randall, 171 F.3d 195, 203 (4th Cir.
1999)). A constructive amendment, also known as a "fatal
variance," happens when "the government, through its presen-
tation of evidence or its argument, or the district court,
through its instructions to the jury, or both, broadens the bases
for conviction beyond those charged in the indictment." Id. at
178 (citing United States v. Redd, 161 F.3d 793, 795 (4th Cir.
1998)). Constructive amendment of an indictment is error per
se and is an independent ground for reversal on appeal even
when not preserved by objection. United States v. Floresca,
38 F.3d 706, 714 (4th Cir. 1994) (en banc).
When considering a constructive amendment claim, "it is
the broadening [of the bases for a defendant’s conviction] that
is important—nothing more." Id. at 711 (emphasis added).
The key inquiry is whether the defendant has been tried on
charges other than those made in the indictment against him.

UNITED STATES v. ROE 17
Here, although the district court mistakenly inserted the
word "police" into its recitation of the language of the statu-
tory offense, the mistake was not a constructive amendment
of the indictment. Rather than broadening the basis for Roe’s
conviction, the instruction identified the particular type of
officer Roe was accused of falsely assuming or pretending to
be. If anything, the instruction narrowed, rather than broad-
ened, the basis for convicting Roe. The instruction was con-
sistent with the offense charged in the indictment, violation of
§ 912 and, as the indictment specifically noted — Roe hold-
ing himself out to be a federal police officer. Because the
instruction did not allow Roe to be convicted of a crime not
included in the indictment, the district court did not errone-
ously amend the indictment in violation of Roe’s Fifth
Amendment rights.3

For the aforementioned reasons, we affirm the judgment of
the district court.
AFFIRMED
GREGORY, Circuit Judge, dissenting:
The majority makes a fundamental mistake today in inter-
preting 18 U.S.C. § 912: holding that it may be properly
applied to an individual who is in fact a federal officer,
though he may have acted outside his authority. The language
makes clear that the statute is only meant to apply to those
who are not federal officers, yet pretend to be. At base, the
statute is not meant to regulate the exercise of authority by
3
In addition to contending that the district court erred in giving the
instruction, Roe also asserts the district court erred in denying his motion
for a new trial, which was based on the same alleged error in the jury
instruction. For the reasons discussed above, Roe’s argument as to the
denial of his motion for a new trial also fails.

federal officers; it is a criminal statute meant to deter and pun-
ish impersonators of federal officers. For this reason, I dissent
from the majority’s opinion and would reverse Roe’s convic-
tion.1
I.
18 U.S.C. § 912 provides:
Whoever falsely assumes or pretends to be an officer
or employee acting under the authority of the United
States or any department, agency or officer thereof,
and acts as such, or in such pretended character
demands or obtains any money, paper, document, or
thing of value, shall be fined under this title or
imprisoned not more than three years, or both.
18 U.S.C. § 912 (2006) (emphasis added). Thus, we have held
that in order to prove a violation of Section 912 under the
"acts as such" prong, the government must show the defen-
dant (1) falsely assumed or pretended to be a federal official
and (2) acted as such. United States v. Guthrie, 387 F.2d 569,
570 (4th Cir. 1967). To "act as such," the defendant must have
asserted his pretend authority in some way. United States v.
Parker, 699 F.2d 177, 179 (4th Cir. 1983) (holding that the
mere statement that one is a federal officer, without more, is
insufficient to show that the defendant "acted as such").2

I concur as to the majority’s conclusions in parts II.A and II.C of its
opinion concerning Sergeant Russell’s testimony and the jury instruction
about the elements of the crime.

In Parker, we expressly distinguished our interpretation of the statute
from the D.C. Circuit’s, which requires that the impersonator perform an
overt act asserting the authority he claims to have. See United States v.
Rosser, 528 F.2d 652, 656 (D.C. Cir. 1976). By contrast, this Circuit also
does not require that the impersonation have an effect on a third party.
Compare United States v. Gilbert, 143 F.3d 397, 398 (8th Cir. 1998) ("To
‘act as such’ would be the equivalent of causing the deceived person to
follow some course he would not have pursued but for the deceitful con-
duct.") (internal quotation marks and citation omitted). Rather, we require
only that the impersonator falsely pretend or assume the office of a federal
officer and attempt to assert that authority in some way.
UNITED STATES v. ROE 19
The majority holds that the evidence at trial was sufficient
to convict Roe under Section 912. It concludes that the jury
could have reasonably found that Roe was not a federal offi-
cer, and, even if he was, the fact that he actually was a federal
officer did not give him license to act as though he had
authority beyond what he actually possessed. Yet, the majori-
ty’s interpretation of the statute, relying principally on an
eighty-nine year old case from the Ninth Circuit concerning
a prior version of Section 912, is not convincing because Roe
was the kind of officer he was charged with pretending to be.
Therefore, even though Roe did not in fact possess federal
authority to take the actions he did on the parkway at the time
of the incident, he could not have pretended to be a federal
police officer because he was one.
A.
First and foremost, I disagree with the majority that the jury
could have reasonably found that Roe was not a federal offi-
cer. It is true that Roe was an employee of Sec Tek, a private
corporation. However, testimony by Thomas Evans, the head
of security at NASA’s Goddard Space Flight Center, estab-
lished, without contradiction, that Roe was a security police
officer there, meaning he was deputized by the federal gov-
ernment to act as a federal police officer — making arrests
and carrying a weapon — on Goddard property. Even though
Roe’s paycheck came from Sec Tek, that does nothing to
diminish the fact that he was imbued with authority by the
federal government and was thus an "employee acting under
the authority of the United States." § 912.
B.
Given that Roe was indeed a federal officer for purposes of
Section 912, the question is then whether he may be convicted
of "pretending" or "assuming" to be a federal officer. Inter-
preting the wording of the statute, the answer must most cer-
tainly be no.
20 UNITED STATES v. ROE
Section 912 prohibits individuals from "pretending" or "as-
suming" to be a federal officer. In interpreting the meaning of
a statute, we give its words their ordinary meaning. Md. State
Dept. of Educ. v. Dept. of Veterans Affairs, 98 F.3d 165, 169
(4th Cir. 1996) (citing United States v. Goldberger & Dubin,
P.C., 935 F.2d 501, 506 (2d Cir. 1991)). To pretend, in the
manner in which it is used in the statute, ordinarily means "to
make believe" or "to hold out, represent, or assert falsely."
Webster’s Third New International Dictionary 1796 (1981).
To assume, in turn, means "to take in appearance only" or
"pretend to have or to be." Id. at 133. Thus, by its wording,
the first clause of the statute criminalizes falsely asserting that
one is a federal officer when one in fact is not.
Notably, the statute does not say anything about asserting
powers or authority that one does not have. The actus reus
under the statute is instead concerned with pretending to be an
officer as such, and then acting in a way that an officer would.
The statute, therefore, is concerned with deterring and punish-
ing those who pretend to be federal officers in order to pre-
vent them from obtaining any benefit accorded to their
pretended status. There is no indication, however, that the
statute is interested in policing those individuals who are fed-
eral officers, but who act outside of their authority. No provi-
sion in the statute criminalizes conduct by those who are
federal officers but pretend to have other authority which they
do not possess. At base, the statute is a criminal sanction, not
a personnel regulation for federal officers who act extradjudi-
cially.
As an illustration of the statute’s reach, consider the follow-
ing example. A male FBI agent is executing a search warrant
on a home and arrests its female occupant for possession of
narcotics. His personnel regulations specifically state that he
does not have the authority to strip search an arrestee of the
opposite sex. Yet, this agent, defying the boundaries of his
lawful authority, orders the woman to undress and submits her
to a cavity search. Would we hold that because he acted with-
UNITED STATES v. ROE 21
out authority, he was "pretending" to be a federal officer and
may be punished under the statute? Certainly not, though he
would likely be liable for aggravated battery and other
offenses.
The key to the foregoing example and the case at hand is
that Section 912 is not concerned with those who in fact are
federal agents but who act without authority, but instead those
who are not and pretend to have federal authority. As in the
example, there are many other statutes which govern the
unlawful exercise of authority by federal officials, just not
Section 912. Thus, while it is certain that Roe did not have
authority to make traffic stops on the Baltimore-Washington
Parkway, he cannot be guilty under the statute for exercising
police power when he did in fact have limited, federal police
powers.
The majority points to United States v. Russell, 271 F. 684
(9th Cir. 1921), to support its conclusion that an individual
who is a federal official can be convicted under Section 912.
In Russell, the defendant was a timber inspector, employed by
the United States Department of the Navy. Russell went to an
apartment, told the occupant, "We are from the federal gov-
ernment," searched the apartment for alcohol, and took $80
from the occupant as a bribe. Id. at 684-85. The Ninth Circuit,
affirming the denial of the defendant’s motion for acquittal,
held that "[t]here can be no question but that an employe [sic]
of one department of the government may be held guilty of
falsely impersonating an officer of another department." Id. at
685. Yet, in that case, the defendant was a timber inspector
and he feigned being an agent of the Bureau of Prohibition.3
He therefore pretended to be a particular federal officer that
he was not, and assumed powers he clearly did not have.
3
The Bureau of Prohibition was the agency tasked with enforcing prohi-
bition in the United Sates. See Lawrence Schmeckebier, The Bureau of
Prohibition, its History, Activities and Organization (1929).
22 UNITED STATES v. ROE
By contrast, Roe was not pretending to be a federal police
officer; he was one. The instrumentalities he used to signal
Corporal Allen to stop — his spotlight, siren, blue lights, and
loud speaker — were all equipment used in his legitimate job
as a federal police officer. There is no argument that Roe
actually possessed the authority to stop Corporal Allen for
speeding on the parkway, yet his actions were not outside of
the type of actions that he would normally undertake on the
Goddard campus working as a security officer deputized with
the power to make arrests and carry a weapon. Compared to
Russell, here the defendant was taking action which, although
beyond his jurisdiction, was of the nature of his position and
authority. In essence, he was behaving in the same way as he
would if he was within his jurisdiction.
Likewise, Roe’s interaction with Officer Zielinski where he
yelled "I’m the police!" and identified himself as a federal
police officer did not represent him to be something that he
was not. In all likelihood, at the time of the encounter, Roe
was attempting not to get shot by identifying himself as one
of the "good guys." No matter his reason for doing so, how-
ever, Roe made no false statement to Officer Zielinski.
Therefore, because Roe was a federal police officer, he
cannot be convicted under Section 912 of pretending to be the
same.
II.
In a case where the individual is the type of federal agent
he represents himself to be, he cannot be liable under Section
912. Otherwise, we would have to interpret the statute to read,
absurdly, that an individual can be convicted of pretending to
be something he actually is. The statutory language makes
clear that Congress did not intend this result. I therefore
respectfully dissent.
