Defendant's conviction for possessing with intent to distribute five grams or more of a mixture containing cocaine base is affirmed where the stop at issue was proper because the "collective knowledge" doctrine--under which the legality of the detention of a suspect by an officer can be supported by information possessed by a fellow officer who requests the detention, even if the requesting officer does not communicate the information to the other officer--applies to traffic stops for misdemeanors as well as stops for felonies.
