Appellant was charged in an indictment with carrying a pistol without a license, possession of an unregistered firearm, unlawful possession of ammunition, and possession of a controlled substance (marijuana). After an evidentiary hearing, the trial court denied appellant’s motion to suppress tangible evidence (the pistol, the ammunition, and the marijuana). Appellant then entered a conditional guilty plea 1 and was sentenced to concurrent prison terms totaling five years; execution of that sentence was suspended, however, and he was placed on probation for thirty-three months. Before this court appellant argues (1) that the evidence should have been suppressed because the citizen informant’s reliability and basis of knowledge were not properly considered, and that if they had been, a Terry stop and frisk 2 would not have been justified, and (2) that the trial court erred by denying his discovery request for an audiotape *1158 of a 911 telephone call made on the day before his arrest, in which someone who may have been that same informant allegedly provided an inaccurate tip regarding the same location. We affirm.

A. The Suppression Hearing
On February 11, 1999, at 9:24 p.m., a telephone call came in to the Metropolitan Police Department over the 911 emergency line. The male caller reported that a man with a gun “in the side of his waist” was standing in front of a house at 646 Newton Place, N.W. The caller said that his last name was Williams and gave the dispatcher his address and telephone number. 3 Williams went on to say that the man with the gun was wearing a grey sweatshirt, blue jeans, and brown Timberland boots. 4 At the conclusion of the telephone call, the dispatcher directed two patrol cars to go to 646 Newton Place. One of these cars was driven by Officer John Hackley.
Officer Hackley testified that he was on duty in the area of 3200 Georgia Avenue, N.W., when he received a radio call in-strueting him to go to 646 Newton Place because of a report of a man with a gun standing outside that address wearing “a grey sweat jacket and blue jeans.” The officer was in a police car only four blocks from 646 Newton Place, so he arrived there in less than a minute. When he reached that address, Officer Hackley saw three men; one of them — appellant—was wearing a grey sweatshirt and blue jeans, but the other two did not match the clothing description given by the dispatcher. 5
Officer Hackley approached appellant and said that he had received a report of a man with a gun and that appellant fit the description given in the report. The officer immediately conducted a patdown for weapons, in the course of which he felt a hard metallic object of a size consistent with a gun. When he lifted appellant’s shirt, Officer Hackley found a loaded pistol in appellant’s waistband and promptly placed him under arrest. A search incident to that arrest yielded a bag of marijuana from appellant’s pants pocket.
At the suppression hearing, the government played an audiotape of the 911 call that precipitated appellant’s arrest. Dur *1159 ing that call, the police dispatcher mentioned to the caller that she had received a similar call from him just a day earlier, but the caller denied it. When the tape finished playing, defense counsel made a discovery request for “the other 911 call,” referring to the call that the dispatcher had received the previous day from someone whom she believed to be the same informant, Williams. Counsel wanted to find out whether this other tape could be used to impeach Williams’ credibility as an informant. The prosecutor responded that the earlier tape was not relevant because the information in the previous call was not known to, or used by, Officer Hackley when he decided to conduct a Terry stop and frisk of appellant. In denying the discovery request, the trial court said that “the question is whether or not this officer was justified in acting upon the call,” and whether the officer “acted based on a description that was accurately given.... [Tjhere was no apparent reason for this officer ... not to act as he did.” 6
At the conclusion of the testimony, defense counsel argued that the evidence should be suppressed under
Florida v. J.L.,
The court denied the motion to suppress because the facts in this case were distinguishable from those in J.L., specifically ruling that the caller “was anything ... but anonymous.” In addition, the court held that the specific information given by the caller — the description of appellant, his exact location, and the number of others present — was sufficient to justify the Terry stop. Moreover, the court noted that the officer arrived just one minute after the 911 call was made, and that he was able to confirm the specific information related to him by the dispatcher. All of these facts, the court said, gave the officer “a reasonable, articulable suspicion to stop the defendant.” The court then concluded that when the officer, in the course of the frisk, felt the gun in appellant’s waistband, he had probable cause to lift the shirt and seize the gun. The discovery of the gun, in turn, gave the officer probable cause to arrest appellant, to conduct a search incident to that arrest, and to seize the marijuana from appellant’s pocket.
B. Post-Hearing Proceedings
On the day after the hearing, appellant filed a written motion asking the court to *1160 reconsider its denial of the motion to suppress. Again citing Florida v. J.L., appellant argued that the motion should have been granted because the government had failed to establish the informant’s basis of knowledge. The court reaffirmed its denial of the motion to suppress and again distinguished the facts in this case from the facts in J.L.:
And I have to say that on the facts of this case they are somewhat remarkably similar to the facts in J.L., except that this case does not present an anonymous tip because the caller gave a name and a telephone number [and an address] which the dispatcher ... seem[ed] to be able to have some recognition of that telephone number as a number that could be checked by saying something like well, you — I got a call from a different location yesterday.
And so, unlike J.L., this was not an anonymous tip.
The court specifically mentioned that the dispatcher had knowledge of the caller and relied on this fact to conclude that the dispatcher knew that she could get in contact with him if the tip was erroneous. The court also noted that the informant could be held “accountable” for the information he gave and that the innocent details of his tip were corroborated. The court did state that the verification of innocent details was “not enough for a Terry stop” in Florida v. J.L., but it was enough in this case because the informant here was not anonymous and because “in this case we have more.”
II
Appellant contends that the trial court improperly applied the totality of the circumstances test,
see Illinois v. Gates,
A. Applicable Legal Principles
Our review of a trial court’s denial of a motion to suppress is limited.
See White v. United States,
Under
Terry v. Ohio,
*1161 where he has reason to believe that he is
dealing with an armed and dangerous individual, regardless of whether he has probable cause to arrest the individual for a crime. The officer need not be absolutely certain that the individual is armed; the issue is whether a reasonably prudent man in the circumstances would be warranted in the belief that his safety or that of others was in danger.
Terry,
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.
Alabama v. White,
Normally, an articulable suspicion arises from an officer’s personal observations while on duty. That was the situation in
Terry v. Ohio,
when an officer saw three men apparently “casing” a store, possibly in anticipation of “a stick-up.”
Terry,
Key factors in applying this test and assessing the value of the tip are the informant’s credibility and veracity and the basis of the informant’s knowledge.
See Gates,
If a tip lacks indicia of reliability, no forcible stop can follow without further investigation.
Adams,
B. The Validity of the Stop and Frisk
In this case the caller identified himself by last name, address, and telephone number, thereby removing the case from the
Florida v. J.L.
line of cases involving unidentified informants.
9
The trial court concluded that, with this information on the record, the caller could be held accountable for a false report — as both the Supreme Court and this court have previously recognized.
See Gates,
We have found tips from citizens sufficiently reliable to justify
Terry
stops even when the caller provides incomplete identifying information. In
Groves
a 911 dispatcher received a telephone call from a man who identified himself by name but gave no address or telephone number. He told the dispatcher that a man currently in a car at a particular intersection had a gun and described the color and make of the car. The dispatcher relayed an abbreviated version of the tip to officers near that location. The officers found a car of that color at the named intersection and noted that, although the make of the car was not an exact match to the tip, it was substantially similar. We held that these facts were enough to establish a reasonable suspicion and sustained the ensuing
Terry
stop.
Groves,
Like Groves, the present case involves an identified citizen informant who made a telephone call to a 911 dispatcher. The identified informant in the instant case, moreover, provided not only his name but also his address and telephone number, thereby enhancing his reliability. The dispatcher then relayed an abbreviated version of the tip to a nearby police officer. That officer was able almost immediately to corroborate the tip, as in Groves, and thus conducted a frisk, found the gun in *1163 appellant’s waistband, and placed him under arrest.
In
Groves
we held that there was an articulable suspicion based solely on the statements of an informant who gave his full name, stated that a man with a gun was at a certain intersection, gave a description of the car the man was driving, and pinpointed the car’s exact location at the moment of the call.
Groves,
C. Appellant’s Specific Contentions
Appellant maintains that this case should not be governed by the relevant case law on citizen informants because the informant in this case (1) was anonymous, (2) was not “unquestionably honest,” and (3) did not provide any evidence of his basis of knowledge. We address each contention in turn.
1. The Identification of the Citizen Informant
Viewing the facts in the light most favorable to the government, as
Peay
dictates,
*1164
Appellant relies mainly on
United States v. Fisher,
2. “Unquestionably Honest”
Appellant also argues that an identified informant’s tip is not entitled to presumptive reliability if it is not “unquestionably honest.” 11 His analysis of the law misses the mark. In the cases he cites in his reply brief on this issue, the presumptive reliability of an identified informant failed because of possible bias or motive to falsify, not because the informant was anything other than “honest.” In particular, there was nothing in this case to suggest that the informant had any bias or motive to falsify information. He was not an estranged spouse, 12 an angry offspring, 13 or a “concerned” neighbor 14 of the defendant — specific situations that may warrant closer than usual scrutiny because of the connections between the parties and their possible desire to harm one another. Furthermore, in those cases there was no information that could be instantly corroborated, as there was here. In the case at bar, the information provided by the caller was corroborated by the police officer within a minute of the telephone call, a fact which dispels much of the doubt (if there is any) about the reliability and veracity of at least a part of the caller’s tip. 15
Appellant further contends that the informant’s identity should have been examined more thoroughly by the police and that the tip should have been subject to greater scrutiny before the officer conducted a stop and frisk because the dispatcher seemed incredulous and possibly thought the informant was lying when he denied having given similar information a *1165 day earlier. 16 During the 911 call, the dispatcher asked the informant several times whether he had called to report the same information the previous day, and each time he said he had not. The dispatcher finally ended the inquiry after the caller denied that he “called this same thing in yesterday,” but “from another location.” 17 Appellant suggests that this exchange should have caused the police to investigate the tip more thoroughly before acting on it. We do not agree. The dispatcher knew the caller’s name, address, and telephone number; furthermore, there was a tape recording of the call. The dispatcher, therefore, would have been able to trace the citizen if his tip was found to be false. Instead, the description of the suspect was corroborated within minutes, suggesting that at least the identifying information he provided was indeed true. 18 Cf. note 15, supra.
3. Basis of Knowledge
Appellant maintains that the trial court erred in finding the tip reliable because the government failed to present any evidence of the citizen’s basis of knowledge.
In
Gates
the Supreme Court held that while basis of knowledge can be an important factor in the totality of the circumstances, a “deficiency” in the basis of knowledge can be compensated by a strong showing of veracity or some other indicia of reliability.
Gates,
Ill
Next, appellant contends that the 911 call received by the dispatcher on the day before the arrest, to which the dispatcher referred in the 911 call that was played for the court and admitted into evidence, could have been used to impeach the caller’s credibility or to show bias. The court’s refusal to let him do so, he maintains, was reversible error.
We are not persuaded that the previous 911 call would have been relevant to any issue before the court at the suppression hearing. Under
Terry v. Ohio,
the standard for determining whether a police officer had a reasonable articulable suspicion is whether “the facts available to the officer
at the moment of the seizure or the search
[would] “warrant a man of reasonable caution in the belief that the action taken was appropriate[.]”
Finally, as the government reminds us, the request for discovery of the tape was governed by Super. Ct.Crim. R. 16. Denials of such requests can be overturned on appeal only for abuse of discretion, and only on a showing that the defense was prejudiced. We find neither abuse of discretion nor prejudice.
See, e.g., United States v. Curtis,
*1167 IV
There being no basis for reversal, appellant’s convictions are all
Affirmed.
Notes
. See Super. Ct.Crim. R. 11(a)(2).
.
Terry v. Ohio,
. When the dispatcher asked him to repeat the phone number, however, the number he gave was slightly different the second time.
. The 911 call was not transcribed, but a copy of the audiotape is included in the record, and both parties quote from it in their briefs. Highlights of the audiotape include the following:
(1) the caller describes the man with the gun outside 646 Newton Place as wearing blue jeans, a grey sweatshirt, and brown Timberland boots; he is said to be standing with "two or three” other men;
(2) the caller gives his last name as Williams;
(3) Williams tells the dispatcher either that he lives at 646 Newton Place, or that his grandmother lives at 646 Newton Place (he says that the gunman is standing "in front of my building, my grandmother’s building,” but also says, "I live at 646 Newton Place”);
(4) Williams gives his complete telephone number to the dispatcher;
(5) Williams asks to have the 911 conversation kept confidential;
(6) Williams informs the dispatcher that there are two children and a girl in front of the building; and
(7) the 911 dispatcher repeatedly says to Williams that he made the same call the day before, but from a different location; Williams denies the truth of the dispatcher’s assertion each time it is made.
The dispatcher’s subsequent radio broadcast referred to a report of "a man with a gun in front of 646 Newton Place, Northwest, wearing a grey sweatsuit, jeans, in front of 646 Newton....”
.The other two men, however, were wearing blue jeans.
. Despite the court’s ruling, defense counsel pressed on, arguing that the basis for the stop was the caller’s credibility. The court rejected this argument:
[T]hat would mean that every time somebody calls 911, that the police have to make some kind of independent judgment about a ... caller’s credibility?
If I’m sitting in my house and think that I see someone breaking into my neighbor’s house across the street, before the police could act, the police would have to make some kind of independent judgment, investigation, about my credibility before they could come to the scene. That's the logical extent of your argument, it seems to me.
So I’ll deny your motion and we’ll move on.
. Defense counsel argued (1) that the last name given by the caller, "Williams,” was a common name that did not adequately identify him; (2) that the caller had provided two different phone numbers, suggesting that the phone numbers were not his; (3) that the address he gave was incomplete, in that it did not include a specific apartment number; and (4) that the dispatcher believed she was being lied to by the informant.
. Reasonable articulable suspicion has sometimes been defined by differentiating it from probable cause.
See Alabama v. White,
. One such case is
Sanders v. United States,
. The government cites a series of cases in which we have held that anonymous in-person citizen tips can be sufficiently reliable to justify a
Terry
stop, or even to provide probable cause for an arrest, even though the citizen provides no identifying information and leaves the scene before the police take action.
See Davis,
.
Gates,
.
See United States v. Phillips,
.
See Dial v. State,
.
See State v. Monis,
. In Florida v. J.L., a case in which the tipster, unlike the caller in this case, was anonymous, the Supreme Court said:
An accurate description of a subject's readily observable location and appearance is of course reliable in this limited sense: It will help the police correctly identify the person whom the tipster means to accuse. Such a tip, however, does not show that the tipster has knowledge of concealed criminal activity. The reasonable suspicion here at issue requires that a tip be reliable in its assertion of illegality, not just in its tendency to identify a determinate person. Cf. 4 W. LaFave, Search and Seizure § 9.4(h), p. 213 (3d ed. 1996) (distinguishing reliability as to identification, which is often important in other criminal law contexts, from reliability as to the likelihood of criminal activity, which is central in anonymous-tip cases).
. The Supreme Court has stated, however, that "reasonable suspicion [justifying a
Terry
stop] can arise from information that is less reliable than that required to show probable cause.”
Alabama v. White,
. The audiotape contains the following:
Dispatcher: Sir, didn’t you ... call the police about this yesterday?
Caller: No, ma'am.
Dispatcher: Yes, you did.
Caller: No.
Dispatcher: I remember.
Caller: No.
Dispatcher: Sir, we’re gonna send the police out there, but you called this same thing in yesterday.
Caller: No, I did not call yesterday.
Dispatcher: You called from another location.
Caller: No, ma’am.
Dispatcher: Okay....
. Moreover, since Officer Hackley had no knowledge of the interaction between the dispatcher and the caller, this information played no part in Officer Hackley’s decision to conduct a stop and frisk.
. Other evidence to the same effect included the urgent tone of the call to 911, the fact that the caller spoke quietly to the dispatcher so as *1166 not to be overheard, his insistence on immediate police response ("can you send the police, please?”), and his stated desire for the call to remain confidential.
. In our view, it makes no difference whether, as appellant suggests, the information available to the dispatcher should be imputed to the officer. Even if Officer Hackley had known (which he did not) of the disagreement between the caller and the dispatcher regarding whether, as the dispatcher claimed, the caller had also telephoned in a tip on the previous day, this would not have deprived the officer of articulable suspicion to make the stop. If such information were imputed to Officer Hackley, he would have known only that there was some question, unresolvable in the limited time available in which to take action, about whether the caller's denial that he had also made another call on the previous day was truthful or not. In our view, the existence of that unresolvable question, standing alone, would not have sufficiently impaired the caller's apparent reliability to preclude a stop.
The caller, as we have noted, had identified himself to the dispatcher by name, address, and telephone number, and the evidence showed that he was exactly where he said he was when he made the call. This was sufficient to make the relatively modest showing required to establish articulable suspicion, and this is true regardless of the disagreement between the caller and the dispatcher regarding a call which may or may not have been made on the previous day.
