Here's where I piss some of you off.
Beware: a dog dies violently in the following video.
Then, I'm angry that the dog owner would set things up so that his dog ran loose. That's on him.
Finally, I wish that someone had snapped an ASP before going toward the dog. Pressuring it into a charge wasn't a good idea.
I almost shot a large dog, the day before yesterday. Somehow, I kept my perfect record of never having to defensively put down a dog in the street. But this one didn't pay attention to the expandable baton that I had snapped out while I stood in a public street. I nearly had to get to deadly force, as I was backing toward my car, before the dog's owner appeared and called the dog off. And I would have gotten criticized. But I've got scars that I will carry for the rest of my life, because I've hesitated, before. When you get bitten, badly, you're not able to do your job. I'm sorry, but the dog's not worth it.
Still, I've tazed dogs which I was later told that I should have shot, to avoid having such issues. (On one occasion, the Taser didn't work, and I had to use my stick to keep me from getting bitten.) I don't WANT to alienate my community from me. I not only work here, and try to serve these people, but I live here. I don't want members of my community worrying that I'm a person who would kill their family pet. It would do harm to my family relations to the community, and to the department's. I don't want to kill a dog. But if I must, I will.
It is not a human. It is an animal. I should not have to endure being bitten before taking action.
And whatever faults those cops may have, shooting a (sadly confused, loyal) animal to prevent getting bitten in the street isn't really one of them. What they did to lead up to that, though, may well be the subject of my scathing criticism, soon.
