This case involves an encounter between a lone police officer and the appellant, clutching in his hand something that “could possibly have been a weapon, a small knife, possibly a gun,” on the third floor of an apartment building known for narcotics trafficking. We affirm the trial court’s ruling that the officer’s stop of the appellant for further investigation was reasonable within the meaning of the Fourth Amendment.
I
Fourteen twenty-nine Girard St., N.W., Washington, D.C., was an apartment building which the police would routinely enter and check for the illegal drug trafficking for which the building was known. On the afternoon in question, Officer Emmett Queen and two fellow officers, in plain clothes, pulled up to the entrance of the building to make such a routine check.1 Appellant was standing in the doorway of the building; as he looked at the officers exiting their car, he “le[ft] the scene rather hurriedly” and went inside the building.
The team of officers entered the building and fanned out to engage in the drug patrolling.2 Officer Queen mounted the staircase to the third floor, where he came upon appellant in the hallway some three feet away. Queen noticed appellant clutching something in his left hand. Queen could not tell exactly what it was but thought it “could possibly have been a weapon, a small knife, possibly a gun.” As Queen approached, appellant turned away from Queen. Thereupon, in a roughly simultaneous time frame,3 Queen identified himself as a police officer, asked appellant to stop, inquired what appellant had in his hand, and, as appellant started walking away without responding, followed and put his hand on appellant’s shoulder, at which time, as he pulled away from Queen, appellant dropped some thirteen small plastic bags to the floor. These subsequently were found to contain marijuana.
Following a suppression hearing, the trial court found that on the facts here, Queen had “articulable suspicion of criminal activity and danger to himself” upon which to base the stop. Hence, the trial court denied the motion to suppress. At trial, a jury found appellant guilty of possession with intent to distribute cannabis in violation of D.C.Code § 33-541(a)(l) (1988). On appeal, a panel of this court reversed the denial of the motion to suppress, 575 A.2d 279 (D.C.1990). We granted the government’s petition for rehearing and vacated the panel opinion. 580 A.2d 1331 (1990).

The basic legal framework here is a familiar one. To justify an investigative detention under Terry v. Ohio, 392 U.S. 1, 88 S.Ct. 1868, 20 L.Ed.2d 889 (1968), the police “must be able to point to specific and
*1320articulable facts which, taken together with rational inferences from those facts, reasonably warrant that intrusion.” Id. at 21, 88 S.Ct. at 1880. This “minimal level of objective justification” is “considerably less than proof of wrongdoing by a preponderance of the evidence.” United States v. Sokolow, 490 U.S. 1, 7, 109 S.Ct. 1581, 1585, 104 L.Ed.2d 1 (1989). In determining whether a Terry stop is lawful, the court must look to the “totality of the circumstances.” Alabama v. White, — U.S. -, 110 S.Ct. 2412, 2416, 110 L.Ed.2d 301 (1990), quoting United States v. Cortez, 449 U.S. 411, 417, 101 S.Ct. 690, 694, 66 L.Ed.2d 621 (1981).4 Even if each specific act by a suspect could be perceived in isolation as an innocent act, “the observing police officer may see a combination of facts that make out an articulable suspicion.” United States v. Bennett, 514 A.2d 414, 416 (D.C.1986). See Sokolow, supra, 490 U.S. at 9-10, 109 S.Ct. at 1586-87 (“Indeed, Terry itself involved ‘a series of acts, each of them perhaps innocent’ if viewed separately, ‘but which taken together warranted further investigation’ ” (citation omitted)); Illinois v. Gates, 462 U.S. 213, 243-44 n. 13, 103 S.Ct. 2317, 2335 n. 13, 76 L.Ed.2d 527 (1983) (“innocent behavior frequently will provide the basis for a showing of probable cause”). In reviewing a trial court order denying a motion to suppress, the facts and all reasonable inferences therefrom must be viewed in favor of sustaining the trial court ruling. Nixon v. United States, 402 A.2d 816, 819 (D.C.1979); Brooks v. United States, 367 A.2d 1297, 1304 (D.C.1976) (where no express findings, appellate court is to “determine if the denial of the motion to suppress is supportable under any reasonable view of the evidence”).
We agree with the trial court that the case before us presented sufficient “specific and articulable facts” to make constitutionally reasonable the police officer’s decision to “detain [appellant] briefly in order to ‘investigate the circumstances that provoke[d] suspicion.’ ” Berkemer v. McCarty, 468 U.S. 420, 439, 104 S.Ct. 3138, 3150, 82 L.Ed.2d 317 (1984) (citation omitted). We review the circumstances surrounding the Terry stop.
A
The officers arrived for the routine patrol of a specific building known for its narcotics trade. As they arrived, the defendant, upon seeing them, rapidly went into the building. Appellant argues that this fact should be discounted, since the defendant may not have been aware that they were police officers and since appellant “merely walked” away, citing Smith v. United States, 558 A.2d 312, 316-17 (D.C.1989) (en banc), and In re D.J., 532 A.2d 138, 141 (D.C.1987). However, the instant case is significantly different. Here, the defendant did not depart from the area of suspected activity but on the contrary went directly toward it, in a manner described at the suppression hearing as “leavpng] the scene rather hurriedly.” Moreover, the movement of appellant occurred previous and not subsequent to the immediate event leading to the stop. The reaction of the appellant thus bears upon the issue as not only a possible reflection of “consciousness of guilt” but also as related to the possible on-going narcotics trafficking within the building itself (such as a warning to such participants of approaching strangers).5 Moreover, the place to which the appellant hurried and where the subsequent confrontation took place was not some generalized neighborhood or even public street where drug activity was rife but rather a specified identified and isolated private locale, known for such traf*1321ficking and regularly patrolled by the police.
Thus, when Queen mounted the apartment stairway to the third floor and entered the third story hallway, he came upon appellant not as a total stranger, not as an apartment dweller just leaving his quarters or strolling the halls, but as an individual who had hastily entered the building shortly before. Furthermore, appellant had not, as might be expected were he a resident, entered the apartment in which he lived but instead was standing in the hallway “clutching something in his hand” at a distance of some three feet from Queen, who was by himself. Queen testified that he thought the object appellant was clutching “could possibly have been a weapon, a small knife, possibly a gun.”6
B
In the District of Columbia, it is an offense to carry “either openly or concealed on or about [one’s] person ... a[n] [unlicensed] pistol ... or any deadly or dangerous weapon capable of being so concealed.”7 D.C.Code § 22-3204 (1990 Supp.). Moreover, as has been often observed, drugs and weapons go together. See, e.g., United States v. Payne, 256 U.S.App.D.C. 358, 361, 805 F.2d 1062, 1065 (1986) (collecting cases); Irick v. United States, 565 A.2d 26, 31 (D.C.1989) (expert testimony that “when you relate to drugs and guns it’s like a marriage”). Therefore, Queen might reasonably suspect not only that a criminal violation was taking place but that his own personal safety was at peril.8 As the trial court stated, when Queen stopped appellant and asked what he had in his hand, Queen “was only addressing what for him was an articulable suspicion of criminal activity and danger to himself.”
It is suggested that such a belief of Queen was not objectively reasonable because no pistol or switchblade knife is capable of concealment by someone who is “clutching something in his left hand.” We cannot as an appellate court make such a finding of fact in contradiction of the stated belief of a trained police officer and in the absence of any such showing in the record or finding by the trial court. See Davis v. United States, 564 A.2d 31, 35 (D.C.1989) (en banc); Wilson v. United States, 444 A.2d 25, 29 (D.C.1982); Giles v. United States, 400 A.2d 1051, 1054 (D.C.1979); D.C.Code § 17-305(a) (1989). Moreover, with respect to other objects which might constitute dangerous or deadly weapons if carried with an intent to so use them and which could be readily concealed, considering the surrounding circumstances discussed above, we do not think that Queen’s concern that appellant might use whatever was concealed in his hand in that manner can be labeled objectively un*1322reasonable as a matter of law. As our sister federal court has cautioned “in judging the reasonableness of the actions of the arresting officer,” the circumstances “are to be viewed through the eyes of a reasonable and cautious police officer on the scene, guided by his experience and training.” United States v. Young, 194 U.S.App.D.C. 377, 379, 598 F.2d 296, 298 (1979).9
C
Appellant makes much of the fact that after the challenge by Queen, appellant began walking away, which should have dissipated any suspicion on Queen’s part as to how the object might be used. We fail to see why as a matter of law, Queen must have been expected to continue his patrolling of the hall without regard to appellant’s possible possession of a weapon, given all the surrounding circumstances, or why the fact that appellant turned away from Queen necessarily indicates that he had no intent to use a weapon against anyone. Cf. Michigan v. Long, 463 U.S. 1032, 1048-52, 103 S.Ct. 3469, 3480-82, 77 L.Ed.2d 1201 (1983) (permissible to search automobile which Terry detainee may reenter after release).
The personal safety of a police officer in a confrontation is a relevant consideration in the Terry equation. Terry itself, albeit in the context of a post-stop frisk, dealt at length with this general issue:
We are now concerned with more than the governmental interest in investigating crime; in addition, there is the more immediate interest of the police officer in taking steps to assure himself that the person with whom he is dealing is not armed with a weapon that could unexpectedly and fatally be used against him. Certainly it would be unreasonable to require that police officers take unnecessary risks in the performance of their duties. American criminals have a long tradition of armed violence, and every year in this country many law enforcement officials are killed in the line of duty, and thousands more are wounded. Virtually all of these deaths and a substantial portion of the injuries are inflicted with guns and knives.
In view of these facts, we cannot blind ourselves to the need for law enforcement officers to protect themselves and other prospective victims of violence in situations where they may lack probable cause for an arrest.
392 U.S. at 23-24, 88 S.Ct. at 1881 (footnote omitted). See Michigan v. Long, supra, 463 U.S. at 1052, 103 S.Ct. at 3482 (“[W]e stress that a Terry investigation ... involves a police investigation ‘at close range’ ... when the officer remains particularly vulnerable in part because a full custodial arrest has not been effected, and the officer must make a ‘quick decision as to how to protect himself and others from possible danger....’ In such circumstances, we have not required that officers adopt alternative means to ensure their safety in order to avoid the intrusion involved in a Terry encounter” (citations omitted) (emphasis in original)); Michigan v. Summers, 452 U.S. 692, 702-03, 101 S.Ct. 2587, 2594, 69 L.Ed.2d 340 (1981) (officer safety a permissible justification for detaining occupant of premises being searched pursuant to valid search warrant); Pennsylvania v. Mimms, 434 U.S. 106, 110-12, 98 S.Ct. 330, 333-34, 54 L.Ed.2d 331 (1977) (per curiam); Adams v. Williams, 407 U.S. 143, 146, 92 S.Ct. 1921, 1923, 32 L.Ed.2d 612 (1972); United States v. Mason, 450 A.2d 464, 466 (D.C.1982) (“protection of the officer making the stop and of innocent bystanders is of paramount importance” and “has been called the rationale of Terry”); Lewis v. United States, 399 A.2d 559, 562 (D.C.1979); Gilchrist v. United States, 300 A.2d 453, 455 (D.C.1973).
We do not say that a concern based on personal safety, standing alone, will necessarily suffice to warrant a Terry stop. However, it is a factor that need not be *1323ignored when considering whether the “totality of circumstances” permits an officer to “detain that person briefly in order to ‘investigate the circumstances that provoke suspicion.’ ” Berkemer v. McCarty, supra, 468 U.S. at 439, 104 S.Ct. at 3150 (citation omitted).
For all the foregoing reasons, we conclude that such a detention was constitutionally permissible here. Hence, the drugs that appellant let loose from his hand could lawfully be entered into evidence, as the trial court held.
Affirmed.
. Officer Queen, the only witness at the suppression hearing, could not recall whether the vehicle in which they were riding was marked or unmarked.
. Each officer went to a different floor.
. The testimony was somewhat imprecise in the exact sequence of events, and that given at the suppression hearing was at points not totally consistent with that later given at trial. An issue might be presented whether when Peay dropped the bags, he was "seized” within the definition of that concept recently set forth in California v. Hodari D., — U.S.-, 111 S.Ct. 1547, 113 L.Ed.2d 690 (1991) (no seizure where fleeing subject not yet within physical control), with respect to which we requested supplemental memoranda from the parties. These memo-randa raised the further issue of the proper use of such trial testimony. Since the trial court’s ruling may be sustained even if Peay had been constitutionally seized by Queen when he dropped the bags, we proceed from that assumption and need not reach the Hodari D. or related issues.
. As the Second Circuit put it, “We view as wise the admonition of the District of Columbia Circuit that ‘the circumstances before [the officer] are not to be dissected and viewed singly; rather they must be considered as a whole.’" United States v. Magda, 547 F.2d 756, 758 (2d Cir. 1976), cert. denied, 434 U.S. 878, 98 S.Ct. 230, 54 L.Ed.2d 157 (1977) (quoting United States v. Hall, 174 U.S.App.D.C. 13, 15, 525 F.2d 857, 859 (1976)).
. Cf. Sibron v. New York, 392 U.S. 40, 66, 88 S.Ct. 1889, 1904, 20 L.Ed.2d 917 (1968) ("deliberately furtive actions and flight at the approach of strangers or law officers are strong indicia of mens rea ") (emphasis added).
. Appellant stresses the use of the word "possibly.” We think it a fair reading of the testimony, especially in light of the repetitive use of the word, that Queen’s use of that word did not reflect a wholly speculative attitude but instead could be descriptive of a variety of possible objects.
. The test to be applied in determining whether an item is a "deadly or dangerous weapon” is whether, under the circumstances, the purpose of carrying the item was its use as a weapon. Nelson v. United States, 280 A.2d 531, 533 (D.C.1971) (per curiam); Clarke v. United States, 256 A.2d 782, 786 (D.C.1969); Criminal Jury Instructions for the District of Columbia, No. 4.81 (3d ed. 1978).
If appellant were in fact armed, he might also, or alternatively, have been in violation of D.C.Code § 22-3214 (1989), which provides in pertinent part:
fa) No person shall within the District of Columbia possess any machine gun, sawed-off shotgun, or ... switchblade knife_
(b) No person shall within the District of Columbia possess, with intent to use unlawfully against another, an imitation pistol, or a dagger, dirk, razor, stiletto, or knife with a blade longer than 3 inches, or other dangerous weapon.
For present purposes, there is no relevant distinction between the two Code sections as to the nature of the weapons they apply to nor the requisite intent, with the exception of those weapons, here an unlicensed pistol or switchblade knife, whose possession or carrying is banned regardless of intent.
.As the trial court noted in its ruling: "[Queen] and two other police officers were in a building where they knew there was a traffic in drugs, and they also knew of the dangers to their own safety inherent in drug trafficking and being in areas where drugs are being sold.”
. The Supreme Court has made the same point in the context of a Terry stop, cautioning that the evidence of suspicion "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.” United States v. Cortez, 449 U.S. 411, 418, 101 S.Ct. 690, 695, 66 L.Ed.2d 621 (1981).
