OPINION
BROOK, Chief Judge.Case Summary
Appellant-plaintiff State of Indiana appeals the trial court's grant of a motion to *342suppress filed by appellee-defendant Robert Bulington ("Bulington"). We reverse and remand.
Issues
The State raises a single issue for review, which we restate as the following two:
I. whether the investigatory stop of Bulington's truck was proper; and
II. whether Bulington freely and voluntarily consented to the warrant less search of his truck.
Facts and Procedural History
At approximately 10:00 p.m. on December 11, 2001, team leader Cassie Oakley ("Oakley") of the Meijer Superstore in Lafayette saw two men standing in the nasal decongestant area of the health and beauty department. Meijer's loss-prevention department had previously advised Oakley to "kind of watch people that are looking at" precursors of methamphetamine such as "nasal decongestants and Sudafed and things like that[.]" Tr. at 6. When the two men declined Oakley's offer of assistance, she telephoned store detective Dan Majors ("Majors") in Meijer's loss-prevention department and informed him that the men were "looking at the nasal decongestants[.]" Id.
The Tippecanoe County drug task force had previously asked Meijer employees to call the Lafayette Police Department ("the LPD") "every time" they saw someone purchase "three boxes or more of cold medicine, antihistamines, Robitussin," or "lithium batteries, fuel, any of the precursors for the manufacture of methamphet-amines[.]" Id. at 11. Using a closed-circuit camera, Majors saw one of the men select three boxes of ephedrine and quickly leave the area. Majors then saw the second man select three boxes of ephedrine. The two men purchased only the ephedrine at different cash registers and "proceeded to act like they weren't together." Id. at 15.
After the first man left with his purchase, Majors called the LPD and notified a dispatcher that the two men had purchased only three boxes of ephedrine 1 apiece at different cash registers. While observing the men with in-store and outside cameras, Majors reported to the dispatcher that they left the store separately, entered the same truck, and removed the tablets from the boxes and put them into Meijer shopping bags. The dispatcher simultaneously relayed this information to Officer Anthony McCoy ("MeCoy"), who had received training regarding the precursors necessary to manufacture methamphetamine.
McCoy responded to the dispatch and entered the Meijer parking lot as the truck was about to exit the lot. Via the dispatcher, Majors confirmed that the two men were in this truck. MeCoy followed the truck out of the parking lot, onto State Road 26, and into a restaurant parking lot. After the truck pulled into a parking space, McCoy activated the emergency lights on his marked police vehicle. Officer Cheever arrived in his own marked vehicle, and the two officers approached the truck.
McCoy spoke with Bulington, the driver, who was "very nervous" and "visibly shaking[.]" Id. at 82. McCoy asked Bulington to exit the truck and requested his driver's license and registration. McCoy retained these items and asked Bulington about his purchase of the ephedrine at Meijer. Bul-ington responded, "[TJhat's what she told me to buy." Id. at 86. Bulington consented to McCoy's request to perform a pat-*343down search of his person, which yielded no weapons. McCoy then asked if he could search the truck. Bulington shook his head yes; when McCoy asked for clarification, Bulington responded that the officers could search the truck. McCoy asked Bulington to stand near Officer Bob Brown, who had also responded to the dispatch.
Inside the truck, McCoy found a Meijer shopping bag containing six empty Meijer-brand packages of ephedrine; an Osco bag containing what appeared to be hundreds of "one milligram ephedrine pills" and six unopened foil packs of pills; a Super Target bag containing, among other items, an eleven-ounce can of an ether-containing substance;2 a plastic tube with tape on one end; a piece of aluminum foil with charring on one side and residue on the other; and two four-packs of lithium batteries.3 Id. at 87-38.
On January 3, 2002, the State charged Bulington with Class B felony conspiracy to commit dealing in methamphetamine; 4 Class D felony possession of two or more chemical reagents or precursors with intent to manufacture methamphetamine;5 and Class D felony maintaining a common nuisance.6 On February 11, 2002, Buling-ton filed a motion to suppress the evidence seized as a result of MceCoy's stop and search of his truck.
On April 1, 2002, the trial court held a hearing on Bulington's motion. On April 28, 2002, the trial court entered numerous detailed findings and conclusions and issued the following order:
The Court finds that the defendant was not violating any traffic laws prior to being pulled over by the officers on this "traffic" stop. The Court is judging the reasonableness of this investigatory stop by attempting to strike a balance between the public interest and the individual's right to personal security free from arbitrary interference by law enforcement. The Court now concludes that this "traffic" stop is defective under the totality of the cireumstances under both the United States Constitution and the Indiana Constitution since the investigatory stop was based solely on a tip made by a cooperative citizen based upon a profile (purchase of three boxes of cold medicine) and where there was no crime or traffic violation committed in the officers' presence. The Court finds the State failed to bear its burden of establishing that the consent to search the vehicle was made voluntarily. The defendant's Motion to Suppress is now granted.
Id. at 60. The State now appeals.7
Discussion and Decision
At the hearing on Bulington's motion to suppress,
*344the State had the burden of demonstrating the constitutionality of the measures it used to secure evidence. In order to prevail on appeal, the State must show that the trial court's ruling on the suppression motion is contrary to law. This court accepts the factual findings of the trial court unless they are clearly erroneous. In reviewing the trial court's decision, we consider the evidence most favorable to the ruling together with any adverse evidence that is uncontradicted.

I. Investigatory Stop
The State argues the propriety of McCoy's investigatory stop of Bulington's truck under the Fourth Amendment of the United States Constitution and Article I, Section 11 of the Indiana Constitution. We address each argument in turn.
A. Fourth Amendment of United States Constitution 9
The Fourth Amendment to the United States Constitution prohibits "unreasonable searches and seizures" by the Government, and its safeguards extend to brief investigatory stops of persons or vehicles that fall short of traditional arrest. However, a police officer may briefly detain a person for investigatory purposes without a warrant or probable cause if, based upon specific and articulable facts together with rational inferences from those facts, the official intrusion is reasonably warranted and the officer has a reasonable suspicion that criminal activity "may be afoot." Terry v. Ohio, 392 U.S. 1, 21-22, 88 S.Ct. 1868, 20 L.Ed.2d 889 (1968).
Cases recognize that reasonable suspicion is a "somewhat abstract" concept, not readily reduced to "a neat set of legal rules." When making a reasonable-suspicion determination, reviewing courts examine the "totality of the circumstances" of the case to see whether the detaining officer had a "particularized and objective basis" for suspecting legal wrongdoing. The reasonable suspicion requirement is met where the facts known to the officer at the moment of the stop, together with the reasonable inferences arising from such facts, would cause an ordinarily prudent person to believe that criminal activity has occurred or is about to occur.
Id. at 641-42 (some citations omitted).
Chief Justice Burger elaborated upon the concept of a "particularized and objective basis" in United States v. Cortez, 449 U.S. 411, 101 S.Ct. 690, 66 L.Ed.2d 621 (1981):
An investigatory stop must be justified by some objective manifestation that the person stopped is, or is about to be, engaged in eriminal activity.
Courts have used a variety of terms to capture the elusive concept of what cause is sufficient to authorize police to *345stop a person. Terms like "articulable suspicion" and "founded suspicion" are not self-defining; they fall short of providing clear guidance dispositive of the myriad factual situations that arise. But the essence of all that has been written is that the totality of the circumstances-the whole picture-must be taken into account. Based upon that whole picture the detaining officers must have a particularized and objective basis for suspecting the particular person stopped of eriminal activity.
The idea that an assessment of the whole picture must yield a particularized suspicion contains two elements, each of which must be present before a stop is permissible. First, the assessment must be based upon all the cireumstances. The analysis proceeds with various objective observations, information from police reports, if such are available, and consideration of the modes or patterns of operation of certain kinds of lawbreakers. From these data, a trained officer draws inferences and makes deductions-inferences and deductions that might well elude an untrained person.
The process does not deal with hard certainties, but with probabilities. Long before the law of probabilities was articulated as such, practical people formulated certain common sense conclusions about human behavior; jurors as factfin-ders are permitted to do the same-and so are law enforcement officers. Finally, the evidence thus collected must be seen and weighed not in terms of library analysis by scholars, but as understood by those versed in the field of law enforcement.
The second element contained in the idea that an assessment of the whole picture must yield a particularized suspicion is the concept that the process just described must raise a suspicion that the particular individual being stopped is engaged in wrongdoing. Chief Justice Warren, speaking for the Court in Terry v. Ohio, swpra, said that, "[this demand for specificity in the information upon which police action is predicated is the central teaching of this Court's Fourth Amendment jurisprudence."
Id. at 417-418, 101 S.Ct. 690 (footnote and citations omitted).
"A reasonable suspicion justifying a limited [investigatory] stop of a vehicle affords a police officer the right to temporarily 'freeze' the situation in order to make investigative inquiry." Bogetti v. State, 723 N.E.2d 876, 879 (Ind.Ct.App.2000). "Reasonable suspicion entails something more than an inchoate and un-particularized suspicion or hunch, but considerably less than proof of wrongdoing by a preponderance of the evidence. Consideration of the totality of the cireumstances necessarily includes a determination of whether the defendant's own actions were suspicious." Crabtree v. State, 762 N.E.2d 241, 246 (Ind.Ct.App.2002). "In judging the reasonableness of investigatory stops, courts must strike a balance between the public interest and the individual's right to personal security free from arbitrary interference by law enforcement officers." Bogetti, 723 N.E.2d at 878. "We review the trial court's ultimate determination regarding reasonable suspicion de novo." Glass, 769 N.E.2d at 642.
At the suppression hearing, McCoy acknowledged that he was dispatched to Mei-jer "in reference to two males purchasing the maximum quantity of ephedrine" 10 and *346testified that while he was en route, the dispatcher
was in contact with somebody from Mei-jer[ ], a representative of Meijer[ ] the entire time we were there and they were giving-kind of giving us the low down or the play by play so to speak of the two gentlemen who had bought [the ephedrine], where they were out, now they're sitting in their vehicle, and that sort of thing until my arrival.
Tr. at 30, 31. Although there is no indication that McCoy was acquainted with Majors or knew his name,11 he did know that the informant was a Meijer employee and was able to confirm that he was following Bulington's truck out of the Meijer parking lot.
Bulington correctly observes that reasonable suspicion "requires that a tip be reliable in its assertion of illegality, not just in its tendency to identify a determinate person." Florida v. J.L., 529 U.S. 266, 272, 120 S.Ct. 1375, 146 L.Ed.2d 254 (2000). Ephedrine is a chemical reagent or precursor of methamphetamine listed in Indiana Code Section 35-48-4-14.5(a). Under subsection (c) of this statute, the possession of two or more such chemical reagents or precursors with the intent to manufacture methamphetamine is a Class D felony. At the time McCoy stopped Bulington's truck, he knew only that the driver and his companion possessed a single methamphetamine precursor. Buling-ton claims that he "went to a store and made a legitimate purchase of three packages of cold medicine. The fact that [his companion] made a similar purchase raises no inference that the purpose of the purchase is to manufacture methamphetamine." Appellee's Br. at 16.
We must disagree. The Tippecanoe County drug task force had asked Meijer employees to notify the LPD if a customer purchased certain quantities and/or combinations of a methamphetamine precursor or precursors.12 Majors informed the police dispatcher that both Bulington and his companion had purchased only three boxes of ephedrine at different cash registers, left the store separately, and got into the same truck. It was reasonable for MeCoy to infer that the two men knew of (or at least suspected the existence of) Meijer's policy of alerting authorities to the purchase of certain quantities and/or combinations of methamphetamine precursors and that they had attempted to purchase one such precursor in a manner calculated to avoid suspicion. See Cortez, 449 U.S. at 418, 101 S.Ct. 690 (explaining that "an assessment of the whole picture" includes "consideration of the modes or patterns of operation of certain kinds of lawhreak-ers"); see also Luster v. State, 578 N.E.2d 740, 743 (Ind.Ct.App.1991) ("A series of acts taken together, each of them perhaps innocent if viewed separately, could warrant investigation.").
*347Under the totality of these circumstances, we conclude that Majors's information was sufficiently reliable to provide McCoy with reasonable suspicion that Bul-ington and his companion were, or were about to be, engaged in criminal activity, i.e., that Bulington and his companion possessed, or were about to possess, two or more chemical reagents or precursors with the intent to manufacture methamphetamine. Compare State v. Eichholtz, 752 N.E.2d 163, 166 (Ind.Ct.App.2001) (holding that officer had reasonable suspicion to stop intoxicated driver without personally observing erratic driving or traffic violations where eyewitness following driver gave name and description of his car to dispatcher; "[The eyewitness] identified himself to the 9-1-1 operator in a manner that he could be held legally responsible if [the officer's] investigation indicated that {the eyewitness] filed a false police report.") and Bogetti, 723 N.E.2d at 878-80 (holding that officer had reasonable suspi-clon to stop suspected intoxicated driver solely on basis of face-to-face encounter with unidentified "concerned citizen" who informed officer that truck driver who had just driven away from restaurant " 'may be intoxicated'"; "Finally, we note that anonymous or unidentified informants can supply information that gives police reasonable suspicion. A tip will be deemed reliable when an individual provides specific information to police officers such as a vehicle description.") with Glass, 769 N.E.2d at 643 (holding that officer did not have reasonable suspicion to stop suspected reckless driver without personally observing traffic violations or inappropriate driving where "at the time of the stop, [the officer] did not know whether the caller [who alerted the dispatcher] was a concerned citizen, a prankster, or an imposter. Further, we cannot discern whether the caller identified himself in such a way as to place his credibility at risk or to subject himself to criminal penalties.") and Washington v. State, 740 N.E.2d 1241, 1243-46 (Ind.Ct.App.2000) (holding that officer did not have reasonable suspicion to stop "possible drunk driver" without personally observing "evidence of drunken or erratic driving" where officer relied solely on tip from anonymous informant who gave description, direction, and license plate number of car; "We accordingly hold that an anonymous telephone tip, absent any independent indicia of reliability or any officer-observed confirmation of the caller's prediction of the defendant's future behavior, is not enough to permit police to detain a citizen and subject him or her to a Terry stop and the attendant interruption of liberty required to accomplish it."), trans. denied (2001); see also Alabama v. White, 496 U.S. 325, 330, 110 S.Ct. 2412, 110 L.Ed.2d 301 (1990) ("Reasonable suspicion is a less demanding standard than probable cause not only in the sense that reasonable suspicion can be established with information that is different in quantity or content than that required to establish probable cause, but also in the sense that reasonable suspicion can arise from information that is less reliable than that required to show probable cause."). The trial court's ruling on this issue is contrary to law.
B. Article I, Section 11 of Indiana Constitution 13
The federal constitution applies to the states through the provisions *348of the fourteenth amendment, which prohibit a state from falling below certain minimal standards. However, Indiana courts have the responsibility of independent constitutional analysis, and the Indiana Constitution may offer protections more extensive than those provided by its federal counterpart. We have interpreted the protections provided by Article I, § 11 of the Indiana Constitution regarding investigatory stops to be consistent with federal interpretation of the protections provided by the Fourth Amendment to the United States Constitution.
Washington, 740 N.E.2d at 1246 (citations omitted). "In resolving challenges asserting this section, courts must consider the cireumstances presented in each case to determine whether the police behavior was reasonable. We require the State to bear the burden of showing that, in the totality of the cireumstances, the intrusion was reasonable." Mitchell v. State, 745 N.E.2d 775, 786 (Ind.2001) (citations and quotation marks omitted).
To reiterate, McCoy received information from a Meijer employee that both Bulington and his companion had purchased only three boxes of ephedrine 14 at different cash registers, left the store separately, and got into the same vehicle. McCoy reasonably could have inferred from Majors's running commentary of the pair's activities that they had attempted to purchase a single methamphetamine precursor in a manner calculated to avoid suspicion. Under the totality of the circumstances, we conclude that it was reasonable for McCoy to conduct an investigatory stop of Bulington's truck to determine whether he and his associate had engaged or were about to engage in the criminal activity of possessing two or more methamphetamine precursors with the intent to manufacture methamphetamine.15 The trial court's ruling on this issue is contrary to law.
Having reached this conclusion, however, we must admit that we are deeply troubled by unwritten store "policies" specifying a seemingly arbitrary quantity of certain household items that customers may purchase without coming under suspicion. We are similarly troubled by the prospect of authorities acting on tips from improperly trained or overly zealous store employees 16 in investigating the spreading scourge of methamphetamine manufacture.17
*349Nevertheless, we cannot ignore that, unlike illegal drugs derived from coca or opium, methamphetamine can be easily manufactured using raw materials and equipment that (with the exception of anhydrous ammonia) 18 are readily available in any drugstore or general retail store.19 As a consequence, thousands of purchases of otherwise "innocent" household items in certain quantities and combinations that onee would have been made without notice or comment now result in heightened surveillance and criminal investigation.20 Faced with this disturbingly Orwellian reality, both the courts and the civil authorities must ensure that Indiana's laws against methamphetamine manufacture are enforced in a manner that does not unreasonably infringe upon the privacy rights of Hoosiers guaranteed by the state and federal constitutions.
II. Consent to Search Truck
We now address the legality of McCoy's search of Bulington's truck. Both the Fourth Amendment and Article I, Section 11 protect against unreasonable searches of a person's effects, including automobiles. See Ammons v. State, 770 N.E.2d 927, 930-31 (Ind.Ct.App.2002), trans. denied. Under the Fourth Amendment, "[a] search conducted without a warrant issued upon probable cause is per se unreasonable." State v. Jorgensen, 526 N.E.2d 1004, 1005 (Ind.Ct.App.1988) (citing Schneckloth v. Bustamonte, 412 U.S. 218, 93 S.Ct. 2041, 36 L.Ed.2d 854 (1973)). "This rule is subject only to a few established" and well-delineated exeeptions. *350One of the specifically established exceptions to the requirements of both a warrant and probable cause is a search that is conducted pursuant to consent." Id. (citation omitted). "When the State seeks to rely upon consent to justify a warrantless search, it has the burden of proving that the. consent was, in fact, freely and voluntarily given. The voluntariness of this consent to search is a question of fact to be determined from the totality of the cireum-stances." Callahan v. State, 719 N.E.2d 430, 435 (Ind.Ct.App.1999) (citation omitted).
"Under the Indiana Constitution, | the State must show that a search was reasonable in light of the totality of the cireamstances." Ammons, 770 N.E.2d at 931 (citation omitted); see also Baldwin v. Reagan, 715 N.E.2d 332, 337 (Ind.1999) ("Rather than employ federal concepts like the warrant requirement and probable cause requirement [in analyzing claims of search and seizure violations under the Indiana Constitution], we require instead that the State bear the burden of showing that, in the totality of the cireumstances, the intrusion was reasonable.").
We note that in its order granting Bulington's motion to suppress, the trial court did not specify whether it reviewed the propriety of the search of his truck under the state or the federal constitution. Neither does the State offer separate state and federal constitutional analy-ses in its appellate brief. Given that we must consider the totality of the cireum-stances surrounding Bulington's consent under either branch of jurisprudence, we conclude that a search to which a defendant freely and voluntarily consents is valid under the Fourth Amendment of the United States Constitution and reasonable under Article I, Section 11 of the Indiana Constitution.
A consent to search is valid except where it is procured by fraud, duress, fear, intimidation, or where it is merely a submission to the supremacy of the law. To constitute a valid waiver of Fourth Amendment rights, a consent must be the intelligent relinquishment of a known right or privilege. Such a waiver cannot be conclusively presumed from a verbal expression of assent unless the court determines, from the totality of the cireumstances, that the verbal assent reflected an understanding, uncoerced, and unequivocal election to grant the officers a license which the person knows may be freely and effectively withheld. Knowledge of the right to refuse a search is one factor which indicates voluntariness.
The "totality of the cirenmstances" from which the voluntariness of a detainee's consent is to be determined includes, but is not limited to, the following considerations: (1) whether the defendant was advised of his Miranda rights prior to the request to search; (2) the defendant's degree of education and intelligence; (8) whether the defendant was advised of his right not to consent; (4) whether the detainee has had previous encounters with law enforcement; (5) whether the officer made any express or implied claims of authority to search without consent; (6) whether the officer was engaged in any illegal action prior to the request; (7) whether the defendant was cooperative previously; and (8) whether the officer was deceptive as to his true identity or the purpose of the search.
Callahan, 719 N.E.2d at 435 (citations omitted).
The evidence is undisputed that three police officers and three police vehicles were present at the seene of the stop; that McCoy had informed Bulington of the rea*351son for the stop and performed a consensual patdown search of his person; and that McCoy had asked for and retained Bulington's driver's license and registration.21 When McCoy asked for Bulington's consent to search the truck, Bulington shook his head "yes". Tr. at 36. When McCoy sought to clarify the meaning of this response, Bulington "said yes that [MeCoy] could search his vehicle." Id. at 52. The totality of these cireumstances indicates that Bulington's consent was not procured by fraud, duress, fear, or intimidation and was not merely a submission to the supremacy of the law; that Bulington need not have been advised of his Miranda rights because he was not subjected to custodial interrogation;22 that none of the officers made any express or implied claims of authority to search without consent; that McCoy had not engaged in any illegal action prior to the request; that there was no indication that Bulington had been uncooperative; and that McCoy was not deceptive as to his true identity or the purpose of the search. See Lyons, 735 N.E.2d at 1185. The record is silent with respect to the remaining considerations mentioned in Lyons but clearly indicates that Bulington's consent to the search of his truck was freely and voluntarily given and that the search was therefore valid under the Fourth Amendment of the United States Constitution and reasonable under Article I, Section 11 of the Indiana Constitution. The trial court's ruling on this issue is contrary to law. We therefore reverse its grant of Bulington's motion to suppress and remand for further proceedings.
Reversed and remanded.
KIRSCH, J., concurs. DARDEN, J., dissents with opinion.. Ephedrine is one of the chemical reagents or precursors of methamphetamine listed in Indiana Code Section 35-48-4-14.5(a) See Ind.Code § 35-48-4-14.5(a)(1).
. According to the transcript, McCoy described this substance as "Snap starting food[.]" Tr. at 38. We presume that McCoy actually referred to starting fluid. See Iddings v.

. On October 22, 2002, our court prematurely issued an opinion in which a majority of this *344panel affirmed the trial court's ruling on Bul-ington's motion to suppress. We vacated this opinion one week later.
. In stating the applicable standard of review, Bulington relies on this court's opinion in Lockett v. State, 720 N.E.2d 762 (Ind.Ct.App.1999), which our supreme court subsequently vacated. See Lockett v. State, 747 N.E.2d 539 (Ind.2001).
. The Fourth Amendment of the United States Constitution provides,
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the places or things to be seized.
. McCoy was the only witness at the suppression hearing to testify that the medication at issue contained ephedrine. See Tr. at 32 ("I had information from Meijer{] that they *346had purchased the maximum amount of ephedrine, packs of ephedrine, there were two individuals who had purchased the maximum amount. ..."). Oakley testified that the two men were looking at "nasal decongestants," id. at 6, and Majors referred to the medication variously as "cold medicine" or "antihistamine." Id. at 14-15.
. Contrary to the State's suggestion, the record does not indicate that McCoy knew that Majors was a "store loss prevention officer{[.]" Appellant's Br. at 7.
. This is not the first time that our court has encountered such a policy. See Dolkey v. State, 750 N.E.2d 460, 461 n. 2 (Ind.Ct.App.2001) ("According to [a Vanderburgh County Wal-Mart store's loss prevention associate], the store's loss prevention department notifies authorities as a standard operating procedure when a customer purchases three boxes of pseudoephedrine tablets or other 'maximum amount[s] of specific precursor{s]' of methamphetamine.").
. Article I, Section of the Indiana Constitution provides,
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable search or seizure, shall not be violated; and no warrant shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the person or thing to be seized.
. The State characterizes six boxes of ephedrine as a "large quantity" of the substance. Appellee's Br. at 6. There is no basis in the record for concluding that six boxes containing an unknown quantity of tablets with an unknown concentration of ephedrine is a "large quantity" of ephedrine. The critical factor in our analysis is the reasonableness of the inference that Bulington and his companion knew or suspected the existence of Meijer's policy of alerting authorities to the purchase of a certain quantity of methamphetamine precursors and that they attempted to purchase the ephedrine in a manner calculated to avoid suspicion.
. We are not concerned here with the purchase of three boxes of ephedrine by a single customer who simply enters and exits the store alone. Such a purchase might well have prompted Majors to alert the authorities; without more, however, it would not necessarily give rise to a reasonable suspicion of criminal activity sufficient to justify an investigatory stop. Nothing would prohibit an officer, however, from conducting a less intrusive investigation to determine whether the ephedrine purchaser might subsequently purchase additional precursors at other stores with the intent to manufacture methamphetamine.
. At the suppression hearing, Majors acknowledged that he would call the LPD if a customer purchased only one tank of propane fuel or duct tape. See id. at 21-22.
