This video doesn't probably show the whole story, no one probably knows what it is. However, it is only reasonable to assume that the guy had given no real reason to be arrested other than just getting on the nerves of the police by filming them. So they do the normal things these days, approach and handcuff. Then kill the guys dog. This country has decided to give guns and a lot of power to largely uneducated people with very few other skills.
I'm a big dog lover and have owned several rotties and in all fairness to the cops they waited until the dog actually went after them before shooting him. If you've ever been attacked by a dog you would understand. Dogs are weapons and control over them at all times is key. Owners fault for not rolling up his windows. Sad video.
At least the cops hesitated until it made a move.
From what I saw the dog charged once or twice then actually jumped up and went for the cops arm. I agree they should have tried mace or a tazer but, until your in that situation with a 100 plus pound dog coming after you it's hard to say how one reacts. I own a pit who is very well trained but, because of her breed cops have 0 tolerance when it comes to the dogs being agressive towards them. Plus the guy's a fuckin" idiot for sticking his nose in a situation that had nothing to do with him. 100% owners fault the dog is dead!
So it's his fault for getting arrested while clearly doing nothing illegal? Plus, to say the dog "charged" is an exaggeration. The cops could have handled that a lot better.
