MEMORANDUM *
We affirm Bert’s convictions. We address all of the issues Bert raises on appeal in this unpublished memorandum. We address the Government’s cross-appeal in a contemporaneously filed published opinion.
*468I. Bert’s Motion To Suppress
We reject Bert’s argument that he was detained and searched in violation of the Fourth Amendment when he and the officers left the train terminal building. We conclude that the officers had reasonable suspicion to detain Bert outside the building and obtained the drugs in a valid search incident to arrest.1
“[T]he police can stop and briefly detain a person for investigative purposes if the officer has a reasonable suspicion supported by articulable facts that criminal activity ‘may be afoot,’ even if the officer lacks probable cause.”2 In determining whether reasonable suspicion supported a detention, a court “must look at the totality of the circumstances of each case to see whether the detaining officer has a particularized and objective basis for suspecting legal wrongdoing.”3 While mere correspondence to a drug courier profile does not provide reasonable suspicion,4 the combination of a profile match with factors such as traveling under an assumed name, or the giving of evasive answers to an officer’s questions, can supply reasonable suspicion.5
It is undisputed that Bert matched a drug courier profile. Moreover, in answering Officer Paskwietz’s questions— while still inside the building — Bert gave Paskwietz a name that was different than that on Bert’s train ticket, a home town that was different than the address on Bert’s identification, and a ticket-purchase date that Paskwietz knew to be incorrect. Under the totality of these circumstances, Paskwietz had reasonable suspicion to detain Bert by the time he and the officers left the building.
Once outside, the officers had probable cause to arrest Bert after he unzipped his shoulder bag and the officers saw within an object wrapped in white plastic that, based on the officers’ experience and training, was consistent with the type of package used to smuggle illegal drugs.6 Under the search incident to arrest exception to the warrant requirement, the officers were then justified in searching Bert’s shoulder *469bag, which was in his “immediate control”7 because it was slung around his neck. Thus, the search of Bert’s shoulder bag, and the events leading up to it, did not violate the Fourth Amendment. Accordingly, the district court did not err in denying Bert’s motion to suppress.
II. Bert’s Request for an Evidentiary Hearing
“An evidentiary hearing must be held only when the moving papers allege facts which are sufficiently definite, clear, and specific to enable the trial court to conclude that contested issues of fact exist.”8 “A hearing is not required on a motion to suppress if the grounds for suppression consist solely of conelusory allegations of illegality.”9
Agent Delaney — who received the confidential information that “Erick Bert” matched a drug carrier profile — stated under oath that the profile did not contain a racial element and that the confidential informant did not inform Delaney of “Erick Bert’s” race. Bert, on the other hand, alleged no specific facts other than his freestanding claim that he was a victim of racial profiling. Thus, Bert offered nothing more than a conelusory allegation of illegality. Accordingly, the district court did not abuse its discretion in denying Bert’s request for an evidentiary hearing.
III. The Expert Testimony
Federal Rule of Evidence 704(b) prohibits an expert from “staffing] an opinion or inference”10 that would “necessarily compel the conclusion”11 that the defendant had the required mental state for the crime with which the defendant is charged. Bert argues that Delaney directly testified that Bert intended to distribute the drugs, or that it necessarily follows from Delaney’s testimony that Bert so intended. We disagree.
Delaney’s testimony is indistinguishable from that of the expert in United States v. Gomez-Norena,12 who “merely testified that possession of large amounts of cocaine is consistent with an intent to distribute it.”13 Such testimony does not amount to an “explicit opinion”14 or inference as to a defendant’s mental state,15 nor does it necessarily compel any conclusion in that regard.16 Thus, the district court *470did not err in admitting Delaney’s testimony.17
IV. Bert’s Motion to Acquit for Insufficient Evidence
We have expressly held that “crack” cocaine “is synonymous with ‘rock’ cocaine.”18 Both Paskwietz and Delaney testified that the substance at issue was “rock” cocaine, either by directly identifying it as such or by agreeing with the examiner’s characterization of the substance as “rock” cocaine. Thus, there was ample evidence from which a rational finder of fact could have concluded that Bert possessed “crack” cocaine.19 Accordingly, the district court did not err in denying Bert’s motion for acquittal.
V. Bert’s Knowledge of the Type and Quantity of Drugs
“Apprendi did not change the long established rule that the government need not prove that the defendant knew the type and amount of a controlled substance that he imported or possessed; the government need only show that the defendant knew that he imported or possessed some controlled substance.”20 Bert’s contrary argument that Apprendi v. New Jersey 21 requires that drug types and quantities must now be viewed as elements of a § 841 offense is unpersuasive. “Apprendi eschews the distinction between sentencing factors and elements of a crime.”22 Section 841 merely has “separate statutory provisions governing [the] substantive offense and [the] sentencing factors,”23 a structure wholly acceptable under Apprendi24 Thus, the district court did not err in instructing the jury that it need only find that Bert knew that he possessed some kind of prohibited drugs.
VI. Bert’s Prior Conviction
“ ‘Under the current state of the law, the Constitution does not require prior convictions that increase a statutory penalty to be charged in the indictment and proved before a jury beyond a reasonable doubt.” ’25 Bert does not dispute that he *471had a valid prior conviction. Accordingly, the district court did not err in enhancing Bert’s sentence even though his prior conviction had not been charged in the indictment nor proven to the jury.
Convictions AFFIRMED.

The Morales en banc panel cited Gomez-Norena several times with approval, *470however, see Morales, 108 F.3d at 1033, 1037-38, which means that the testimony in Gomez-Norena — and, by direct analogy, this case — is admissible under the “necessarily compels” standard.
. We note that our recent holding regarding expert witness testimony in United States v. Pineda-Torres, 287 F.3d 860 (9th Cir.2002), is not applicable to this case. In Pineda-Torres, the issue was whether the defendant knew that marijuana was hidden in his car. Id. at 863-64. The Government introduced expert testimony regarding the structure of large drug trafficking organizations in an attempt to establish knowledge, even though there was no evidence that the defendant was part of a large drug trafficking organization. Id. at 864. In this case, however, Delaney's testimony concerned the properly admitted and undisputed evidence of the quantity of drugs involved.
