Well to start out a statement with an insult kind of throws you're credibility out the window, so you're dumb uneducated moron.
What it looks like and what it is are two different things. Not to mention it's an opinion, "It looked cute, so I did not think it would attack?" I wonder how many people have said that //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
Police are people just like you and I, well mayby not as much as you atleast. I know a couple cops and have done aug training myself, and we were always taught, its the officer's safety first. If a dog is running up to you and does not stop, you will put it down. There is a thing called a use of force ladder. I'm not a judge or jury, but most likely he will not be punished, and if he is, just a slap on the wrist.
Yes, mace, or a batton would have worked, but he chose to use a gun. That's the only fact here.
