My comment about the small dogs had nothing to do with the officers and deadly force. Someone posted about a cocker threatening a mailman and the mailman either sprayed or kicked it (or something like that, I didn't want to read back that far again to make this reply) and said cockers are sweet dogs. I disgreed based on my wife's experience with them. I agree, a cocker isn't a life threatening dog and a good kick should stop it. But then, I'm a bad guy because I kick a sweet cocker who decided he wanted to chomp on my leg, like that mailman did?
A big friendly dog running around the neighborhood? The police don't know that. If the dog was so friendly then the neighbors who called the police in the 1st place should have stepped up and said hey, he's so and so's dog, let me take him home. The neighbors felt threatened so the called the police. The police tried capture the dog because AC was 30 minutes away and they decided that the dog was too much of a risk to the kids in the neighborhood to wait that long. They didn't have the tools AC uses to keep a dog from getting at you like that noose stick thing. The police were trying to catch him and he lunged at one, and he took defensive action. I think it's sad that someone's pet got killed, but I stand by my point that it's entirely the owners fault for allowing the dog to be outside unsupervised in the 1st place.
I agree, the police were not properly trained for this incident. They have since taken classes on how to deal with potentially aggressive dogs. As far as pepper spray goes, you need to get way too close to a dog to use it. If there is an aggressive dog, I'm not getting 2' away from it's head to spray it, and hope that the wind isn't blowing back at me, and I get a direct hit on the dog. It might work for a little dog but a 100+ lb dog needs to be approached with a little more caution and might require deadly force sooner rather that later.
As far as the PCP guy goes, sure, the police aren't going to start shooting right off the bat. They didn't in the dog incident either, it was only when the dog made what they considered an aggressive move towards them that they reacted that way. A person on PCP can be extremely dangerous, and using things like spray and tasers often doesn't work when they become violent, so if deadly force was needed to protect the officers and the public, then that's what they should do.
