If you're going to poke me, at least buy me a drink first....
A cop friend of mine told me cops like to do it to trick people. leo says "You're free to go, but would you mind if i take a look in your car?" people hear the "you are free to go part" and figure They are already free so why not? Then when the leo finds something they are all like "ah ha i got you" and the person says "but you said I was free to go" leo replies "not now youre not" Its one big mind game.
