Can a police officer improperly stop a vehicle for a routine traffic stop and seize cocaine with a street value of $200,000?

criminal possession of a dangerous drug in the fourth degree because the police officer improperly stopped defendant's vehicle for a routine traffic stop without reasonable suspicion]; cf People v. Robinson, 97 NY2d 341 [2001] [holding that where a police officer has probable cause to detain a person temporarily for a traffic violation, that seizure is lawful even though the underlying reason for the stop might have been to investigate some other matter]). Whether the police officer reasonably suspected a traffic violation had occurred or had probable cause to believe a traffic violation has occurred and which standard is to be applied in this case is properly left to the hearing court.
