Following a three-day trial in the District Court for the District of Massachusetts, appellants Orlando Rodriguez and Raymond Vargas were convicted under 21 U.S.C. §§ 841(a)(1) and 846 of conspiracy to possess quantities of cocaine and heroin with intent to distribute. On appeal, they each allege that the trial judge erred in (1) refusing to suppress certain evidence seized in the course of their warrantless arrest and (2) denying their respective motions for judgment of acquittal. Rodriguez also challenges the court’s refusal to suppress various items recovered from a motel room upon execution of a search warrant.
I.
The case revolves around the activities of four individuals: Jorge Crespo, Armando Diaz, and the two appellants. 1 The Drug Enforcement Administration (DEA) already had information concerning three of these individuals prior to the events in question. Two informants had reported to the DEA that Crespo and Diaz were major narcotics traffickers from New York, and that Cres-po travelled to Boston almost weekly carrying large amounts of cocaine and heroin. Previous DEA investigation had revealed that Crespo often stayed in Boston at the 1200 Beacon Street Motel-a location known to the DEA, from its own experience and from Brookline Police reports, as an occasional drug distribution point. In addition, the DEA had learned from an assistant district attorney in New York that Crespo had three cases pending there involving the sale of cocaine, that Diaz served as Crespo’s bodyguard during drug transactions, and that Diaz himself had been arrested in New York for narcotics violations. 2 Rodriguez was also well known to the DEA. Four corroborated sources had reported that Rodriguez was a major cocaine and heroin trafficker in the Boston area and that Cres-po and Diaz were his suppliers. DEA agents had stopped Rodriguez and searched his car on a previous occasion, but had uncovered no evidence of unlawful conduct.
On August 2, 1979, Special Agent Boeri received a call from a reliable informant *893 who reported that Crespo and Diaz were in Boston to meet with several major narcotic traffickers from the local area. Despite the informant’s failure to disclose the location of the meeting or the identity of the other participants, Special Agent Keaney suspected, in light of the DEA’s prior information, that the meeting would occur at the 1200 Beacon Street Motel and that Rodriguez would attend. After learning from a telephone call to the motel that Crespo had checked into room 126 at 11:00 the previous evening, Keaney initiated surveillance of the room at approximately 12:30 that afternoon.
Agent Simpkins, disguised as a motel employee, went to room 126 for the ostensible purpose of collecting the day’s rent. Appellant Vargas answered the door, gave Simp-kins the rent and a tip, and received a receipt. The lights in the room were off and the shades were drawn. While standing in the doorway, Simpkins saw nobody else in the room and no signs of criminal activity. Thereafter, the agents observed someone, whom they could not identify, intermittently draw back the window shades partway and peer out.
At approximately 2:00 P.M., Rodriguez and Diaz arrived at the motel in Rodriguez’s car. They proceeded directly to room 126, which adjoins a balcony facing the street, without passing through the motel lobby. Rodriguez knocked on the door, but then immediately went to a phone booth where he appeared to place a short call. With Diaz waiting at the door to room 126, Rodriguez returned to his car and extracted from the trunk a white bag containing a long, box-shaped object. Carrying the bag with two hands, Rodriguez then rejoined Diaz and entered the room. Several minutes later, Vargas stepped outside, scanned the street momentarily, and walked out of the agents’ view. He returned shortly and reentered room 126 carrying an orange cylindrical object which the agents could not then identify.
Approximately twenty-five minutes after Rodriguez and Diaz had arrived, Rodriguez and Vargas exited room 126 and walked to Rodriguez’s car. Rodriguez crumpled up the white bag, now apparently empty, and discarded it. As he approached the car, he also appeared to tuck something under his shirt. Rodriguez and Vargas drove away, and three agents in two cars followed. During the course of this “moving surveillance,” Vargas several times turned around and peered out the rear window. At one point, Vargas looked backwards directly at the pursuing agents. Almost simultaneously, the vehicle veered sharply to the right around another car and then back into the left lane, increasing its speed slightly. Rodriguez’s vehicle was then travelling 30 — 45 miles per hour and was not in violation of any traffic laws. Nonetheless, the agents decided to stop it, believing that Vargas had recognized them, that Rodriguez was attempting to elude them, and that-based on their earlier observations-the two were probably in possession of narcotics. In the course of ordering the appellants out of the vehicle and placing them under arrest, the agents observed on a shelf beneath the glove compartment three packages of mannite-a commercially available laxative commonly used as a cutting agent for heroin and cocaine-and several small amber bottles of a type frequently used to carry those drugs. After being read the Miranda rights, Rodriguez volunteered that he owned the car but denied ownership of the mannite and amber bottles. A pat-down search of both appellants revealed no drugs or weapons; Vargas, however, had a key to room 126 in his pocket. Rodriguez consented to a search of the vehicle’s trunk, which was found to contain a shoulder holster, a bullet-proof vest, and a “dent puller.” 3 Upon discovering these items, the agents subjected the appellants to a partial strip search which uncovered nothing further.
Meanwhile, surveillance at the motel had continued. Approximately ten minutes af *894 ter Rodriguez and Vargas had departed, Crespo and Diaz stepped out onto the balcony and scanned the street. Crespo walked to the parking lot behind the motel and returned with a small white box which he handed to Diaz. After again looking about intently, they reentered the room separately. The agents then gained access to room 125, adjacent to the one under surveillance, and with their front door slightly ajar overheard whistling, men talking in a foreign language, and a metallic clanking sound. Agent Vinton attributed the latter to a triple beam balance scale, based on his experience, as a narcotics agent, with some two dozen such devices.
At approximately 4:30 P.M., Crespo and Diaz walked out onto the balcony and were immediately arrested. In the course of securing the room pending issuance of a search warrant, Agent Vinton spotted a triple beam balance scale in its box on the floor. Crespo was found to have the rent payment receipt that had earlier been given by Agent Simpkins to Vargas. The subsequent search of the room, conducted at approximately 9:30 that evening, uncovered the following items: 693 grams of cocaine, 43 grams of heroin, $8,900 in cash, a triple beam balance scale resting in an open box, an orange hydraulic pump, a large bag of lactose, and a small, empty white box with the word “lactose” written on its label. Lactose is a common cutting agent for heroin and cocaine. A hydraulic pump of the type seized is frequently employed to compress cocaine to make it appear of higher quality. The pump was missing a small component, and there was conflicting testimony at trial as to whether it was operable in that condition; in any event, none of the cocaine recovered had been compressed. Most of the cocaine was fifty percent pure and a small portion of it was seventy-five percent pure. Since cocaine sold on the streets is typically only fifteen percent pure, and given the large amount of lactose seized, the agents inferred at trial that they had interrupted Crespo and Diaz before the cutting process had been completed.
Finally, the white paper bag which Rodriguez had discarded was recovered and found to contain pieces of cardboard. Agent Keaney reconstructed the cardboard pieces and found that they formed the packaging material for the type of triple beam balance scale seized in the motel room.
II.
Based on the evidence presented at the suppression hearing, the district court concluded that the DEA agents initially detained the appellants solely for the purpose of conducting an investigatory stop, and that the decision to arrest them was made only after the mannite and amber bottles were spotted in the car. Accordingly, in deciding whether those objects and the motel key found on Vargas should be suppressed, the court engaged in a two-step inquiry: it first analyzed the propriety of the stop under the “reasonable suspicion” test annunciated in
Terry v. Ohio,
A.
Our review of the entire record discloses a paucity of evidentiary support for the trial court’s finding that an investigatory stop preceded the arrests. When the decision was made to stop the appellants, Agents Boeri and Simpkins pulled alongside their vehicle and motioned to them to pull over. Agent Vinton, in the second car, pulled up alongside the passenger side of Rodriguez’s car so that the door could not be opened. From his seat, Vinton placed his badge against the window and instructed the appellants to put their hands up. *895 Agent Boeri then asked them to step out of the car and, within thirty seconds of the stop placed them under arrest. Although, curiously, the various agents were never directly questioned about their purpose in stopping the appellants, Boeri did express his belief that the vehicle contained narcotics-based on the report that Rodriguez had stuffed something under his shirt upon leaving the motel, the seemingly evasive driving pattern, and the prior surveillance in general. The only evidence suggesting that an investigatory stop was intended- and that the arrests were triggered by the objects spotted in the car-derives from Boeri’s statements that he observed 4 and recognized 5 the mannite before advising the appellants they were under arrest. In subsequent testimony, however, Boeri indicated that the observation of the mannite and the arrest of the appellants-rather than being sequential events bearing a causal relationship-occurred simultaneously in a manner described as “all ... in one motion.” 6
We need not decide, however, whether the trial court’s finding was clearly erroneous. The appellants do not dispute, and we have no difficulty in concluding, that the agents had sufficient grounds to temporarily detain the appellants, at least for the purpose of questioning.
7
The activities observed at the motel and during the moving surveillance, when coupled with the agents’ prior information,
8
constituted “specific and
*896
articulable facts,”
Terry v. Ohio,
B.
“Probable cause exists where ‘the facts and circumstances within [the arresting officers’] knowledge and of which they had reasonably trustworthy information [are] •sufficient in themselves to warrant a man of reasonable caution in the belief that’ an offense has been or is being committed.”
Draper v. United States,
Had the individuals under surveillance been complete strangers to the DEA agents, these actions alone would not have afforded probable cause to arrest. 12 As noted, however, the DEA had received a varied collection of reports concerning the defendants from both confidential informants and other sources. The information from the former group fell into three categories: (1) two informants had reported that Crespo and Diaz were major narcotics traffickers from New York and that Crespo travelled to Boston almost weekly with large amounts of heroin and cocaine; (2) four informants had stated that Rodriguez was a major heroin and cocaine trafficker in the Boston area and Crespo and Diaz were his suppliers; and (3) a single informant had reported on August 2, 1979, that Crespo and Diaz were in Boston to meet with several local narcotics traffickers. In addition, the DEA had learned from an assistant district attorney in New York that Crespo had three cases pending there involving the sale of cocaine, that Diaz served as Crespo’s bodyguard during drug transactions, and that Diaz had also been arrested for narcotics (actually firearms) violations. Rounding out the DEA’s information was the Brookline Police report that the 1200 Beacon Street Motel-which Crespo often visited, according to prior DEA investigation-was an occasional drug distribution center.
As the district court appeared to recognize, and as the government concedes, the informants’ tips all failed to comport with the two-pronged test established in
Aguilar v. Texas,
This is not necessarily a fatal flaw, however, for the government does not-and quite clearly could not-rely solely on this information to establish probable cause. Instead, it views the various tips as relevant factors which, in conjunction with the DEA’s other information and independent surveillance, provided grounds for the arrests. We agree that the informants’ reports can be considered in the probable cause determination notwithstanding their shortcomings under the
Aguilar
test. In
Spinelli v. United States,
The inquiry thus becomes whether all of the information provided to the DEA agents, together with their personal observations, sufficed to establish probable cause to arrest the appellants. We find the question a close one. The tip received on August 2, 1979, although important in triggering the DEA surveillance, contributed only marginally to the probable cause determination. The information provided was fully corroborated by the confirmation of Cres-po’s registration at the motel and by the arrival of Rodriguez and Diaz. But these events by themselves proved little, since the informant did not describe the purpose of the meeting. To infer solely from this tip, even as subsequently corroborated, that criminal activity was afoot would have been entirely conjectural.
The remaining information, however, proved more inculpatory and was sufficient in our view to “permit the suspicions engendered by the [DEA’s surveillance] to ripen into a judgment that a crime was probably being committed.”
Spinelli v. United States,
III.
The appellants’ remaining contentions can be dismissed more summarily. First, Rodriguez challenges the district
*899
court’s denial of his motion to suppress the evidence seized at the motel room pursuant to a search warrant. We agree with the lower court that the contested search did not implicate Rodriguez’s fourth amendment rights and that he therefore lacked “standing” to mount this challenge. Even if conspiracy to possess narcotics could be deemed a possessory offense, the Supreme Court has recently abolished the rule of automatic standing that formerly applied in such cases.
United States v.
Salvucci, — U.S. —,
Second, both appellants challenge the denial of their respective motions for a judgment of acquittal. In assessing the correctness of such a denial, we must view the evidence considered as a whole, including all inferences that may reasonably be drawn therefrom, in the light most favorable to the government, and must then determine whether a reasonable person so viewing the evidence could find guilt beyond a reasonable doubt.
United States v. Fortes,
Affirmed.
Notes
. Crespo and Diaz were indicted on the conspiracy counts and, in addition, were charged with actual possession of cocaine and heroin with intent to distribute. The record states that Crespo “defaulted” prior to trial without any explanation of what constituted the default. Diaz was convicted on all four counts but has not joined in the present appeal.
. In fact, Diaz had been arrested for firearms, not narcotics, violations.
. At trial, the items found in the vehicle’s trunk were excluded from evidence out of concern for their prejudicial impact. There was no explanation of “dent puller.”
. Q. Now, the arrest, agent, to which you have previously testified, the arrest occurred after the defendant was extracted from the vehicle?
A. Yes, as we got them out of the car, yes, sir.
Q. Did you see that Mannite prior to telling the defendant [sic] they were under arrest?
A. Yes, sir, I did.
. Q. And was that [mannite] readily recognizable to you as what you have testified to as a cutting agent?
A. I have seen the packages before. I knew what they were the minute I saw them.
. Q. Now, at the time you stopped Mr. Rodriguez’ car on Bynner Street or South Huntington-which street was it, by the way?
A. Bynner.
Q. Did you tell them at that time, immediately, that he [sic] was under arrest?
A. Yes, ma’am.
Q. And this was before you saw the Man-nite and amber bottles?
A. It was all sort of in one motion. Advised him he was under arrest, to get out of the car, and at that time I was looking in the car and I saw the Mannite and bottles.
This latter testimony occurred at trial, and a question arises as to whether we may consider it in reviewing the denial of a motion to suppress. It apparently is settled law “that the validity of an arrest or search can be
supported
by evidence which was adduced at trial even though this was not presented at the pretrial suppression hearing.”
United States v. Canieso, 470
F.2d 1224, 1226 (2d Cir. 1972) (emphasis added)’
accord, United States v. Bolin,
On the other hand, the use of trial testimony to undermine the validity of an arrest or search is apparently discouraged, at least when the motion to suppress has not been renewed and reconsidered during the course of the trial. See 3 W. LaFave, Search and Seizure § 11.7(c) (1978) and cases cited therein. If so, we would be compelled to overlook Boeri’s trial testimony; Rodriguez’s attorney did object to the introduction at trial of the mannite “on the prior grounds already argued to the Court,” but even if this could be construed as a renewal of the motion to suppress, it occurred before Agent Boeri gave the testimony quoted above. In light of our disposition of the fourth amendment claim, however, we need not resolve this procedural issue, and we thus express no opinion with respect thereto.
. We need not decide whether a frisk of the appellants would also have been appropriate at that time, since the pat-down search occurred subsequent to their arrest.
. In
Adams v. Williams,
.
Compare, e. g., United States
v.
Ramos-Zara-gosa,
. That the agents subjectively intended to effect an arrest should not be controlling when the objective circumstances are consistent with an investigatory stop. Several courts have gone a step further by ruling that, even where an officer formally makes an arrest for which probable cause is lacking, a subsequent search which is no more intrusive than that permitted under
Terry v. Ohio
is lawful if there were in fact adequate grounds for a stop and frisk.
See, e. g., People
v.
Baker,
. A DEA agent is specifically authorized to “make arrests without warrant ... (B) for any felony, cognizable under the laws of the United States, if he has probable cause to believe that the person to be arrested has committed or is committing a felony____” 21 U.S.C. § 878(3) (Supp.1979).
. We recognize that each of these factors was also susceptible of innocent interpretation. Motel rooms are often the site of legitimate business and personal meetings. The knock on the door may not have been heard by the occupants, necessitating telephone contact from the would-be callers. The objects carried into the room were unidentified. The peering about may have been nothing more than aimless restlessness. The mannite may actually have been used as a laxative. As for the abrupt driving maneuver-we remind ourselves that the incident occurred in Boston.
. Although
Aguilar
involved the sufficiency of an affidavit submitted in support of a search warrant application, its test is equally applicable to a determination, made on the basis of testimony at a suppression hearing, as to the lawfulness of a warrantless arrest. See, e.
g., McCray
v. Illinois,
. Nor do the informants’ tips here constitute simply conclusory assertions of criminal reputation, which the
Spinelli
Court dismissed as unworthy of consideration. The affidavit there contained an allegation that Spinelli was “known” to the affiant and to other law enforcement officers as a gambler and an associate of gamblers. The Court regarded the statement as “a bald and unilluminating assertion of suspicion that is entitled to no weight in appraising the magistrate’s decision.”
. Since Vargas has not challenged the motel room search, we need not decide whether his presence in the room when Agent Simpkins gained entry, his payment of the day’s rent, and his subsequent possession of a room key were sufficient to create such an expectation of privacy on his part.
