After consenting to a search of his vehicle. HELL NO!
Never ever, never, never, never give consent. Give them consent to allow you to call your lawyer and have him present. Otherwise, tell them to get a dog, get a news crew, get a f@cking warrant. NEVER !
Makes me wonder: Why the heck would a cop want to search the car of a 72 year old man? The only reason is to FIND something to bust him for.
