During the incident? Don't question... Yes sir, no sir, here is my id sir. Amazingly? I've never been tazered after more than a few encounters... Funny how that works.
Something wrong happens? That's what lawyers are for... you can fight, but only if you are still alive.
And this guy was on parole? DOUBLY reason to yes sir, no sir... Not that police are perfect and never wrong, but just like this situation where it's possible both sides made mistakes? You still made mistakes and woops there goes your parole.
