I have extensive experience with all sorts of dogs.
Socialized dogs frequently behave as they do in a pack. When a new "member" appears, they will move to make acquaintance - this should not be mistaken for aggressiveness. My golden retriever will even hug people he just met.
There are many visual cues given by dogs that tell of their mindset (Is the dog's tail wagging? Are his ears lying back? Is he smiling or bearing teeth?). It doesn't take much to recognize them, and people trusted with the use of lethal force who can expect to encounter dogs should be trained to recognize them.
There are charts of dog "language" Here is a small example of one even though the print may be too small to read here:
"I saw the guy leave while the cops were interrogating me," he said. "I just assumed it was another police officer."
What kind of account should he be held to?
By the way, shooting a dog charging you is one of the hardest things to do. Test yourself: take a 2 liter pop bottle, tie a 50-60 foot string to it. Have a person stand behind you and run rapidly away from you so that the bottle comes directly at you. Try to hit the bottle.
"The first bullet hit the ground close to me. The second shot hit the driveway. Then he shot and killed my dog right in front of me."
Do you agree he put the homeowner and possibly the other officers in danger?
Funny you'd mention that.
A while back, I was in my backyard, minding my own business, when I turned around, and what should I see, but a big Akita slowly moving in on me.
I tried to avoid "any sudden moves" as I drew my .45 and aimed it at him. He continued approaching me, and then lowered his head, wagged his tail, and skittered under the swingly lawn chair, and looked up at me with doleful eyes.
I ended up bringing him indoors, and we tried to find out who owned him. He had busted a big chain attached to his collar (he was ne strong dog!) and was obviously lost, and scared. We ended up hoping no one would claim him. He was a great dog. Then, when the weekend was over, the county shelter called to let us know that the owner was frantic.
My wife cried for days after we returned him.
If I was a "new breed" cop, the story would have had a much shorter ending, eh?
If the dog had turned out to be as agressive as he appeared to be at first blush (strange dog, big, aggressive breed, on my property, out of the blue, moving in on me), I would have been able to drop him in an instant.
The difference is, I waited to see if that instant was gonna happen before I "made it happen."
If you're standing there with a weapon aimed at a dog, you're in a pretty good position to deal with the situation should it turn ugly. You're also in a good position to not kill the dog "just in case" it might turn ugly.
These guys are trained to have the "shot first, ask questions later" mindset.
This is NOT good for society. Not in the least.
Give me a break folks, this is a conservative list. This is not a list where you are the only ones allowed to make mistakes.
As a rule, when civilians "make mistakes", people (and their pets) don't tend to die.
If they did, there'd be hell to pay. We, you see, are not above the law.
And statistically, in "armed encounters", civilians have a dramatically better track record of not shooting the wrong guy.
(Yes, yes, I know that "the police are civilians too", but more and more they don't recognize that fact. The militarization of the police is a frightening thing to watch happen.)
Test yourself: take a 2 liter pop bottle, tie a 50-60 foot string to it. Have a person stand behind you and run rapidly away from you so that the bottle comes directly at you. Try to hit the bottle.
In that case, I'd suggest more range time.
BTW, is that bottle trained to not be gun-shy? Do you assume that most dogs are trained to be broken of that inherent quality? If so, why?
My Rottie hears the hammer click on my .45 and he cowers and scoots away, real low, real fast. Why? Because, once, a couple of years ago, he heard me fire the weapon when he was standing about ten feet away. He's never forgotten that, and he knows the click preceeds the boom.
I kinda doubt that most scumbag perps have trained their dogs to stand fast when they hear firearms discharge. A shot at an approaching dog, even if it misses, is likely to deter any attack, IMO.
