No arrogance and definitely not ignorant. I understand boundaries especially when involving police....and if I lived in California, I definitely would avoid any and all confrontation with them.

The guy is definitely a dumbass and a jerk. That does not make putting him in handcuffs ok.
What do you think they would have done if he had gotten in his car and left?
