From the CSM on the Gates arrest:
“The rule is, if a police officer stops you in a car or on the street, he’s the captain of the ship, and whatever he says goes,” says Jim Pasco, executive director of the Fraternal Order of Police’s legislative division. “If you’ve got something to address, do it later. Do what he says, or else only bad things can happen.”
I think I see where this guy’s coming from, but it really sounds bad. If an officer asks me to stop doing something constitutionally protected (say, taking pictures), I can’t argue the case on the spot? I either give up my rights or go downtown?
