What I see is an anti-gun cop who is totally out of control.
Not only do I hope he gets fired,
but the his "victim" sues the crap out of him, his do nothing partner and the PD.
FWIW, Arizona is another state whee you have to notify the officer if you're armed. permit or no permit as we don't need a permit here.
What does puzzle me is why was the passenger in the back seat and them talking to a known hooker and Her pimp, if that's what they were. I would imagine that would raise up some suspicion to any cop, but not to the level of rage he showed.
Most likely, his police union will keep him from being fired or out of jail thus allowing him to go work for some other PD and threatening some other citizen.
He just might end up getting a civilian killed. I got the feeling he wanted to cop someone anyway. I once knew a deputy who stated he wanted to do in a bad guy just for the fun of it. Dunno if he ever got his wish.
