I have found no reference to the distance in either of the posted articles. Where did you read that it was "within arm's reach"?KD5NRH wrote:"He shouldn't have reacted so fast" when the dog was already within arm's reach. Great thinking there.
I am pretty handy with a pistol. Having played Longtooth's "shoot the dog" game at the range, I am confident that the dog was not behaving aggressively, because the officer hit it with one shot. A moving dog is just too difficult a target to hit.
I also find it a shame that this man has raised his children to be so terrified of dogs -- and they obviously learned it from him.
As I mentioned earlier, my wife is a groomer, and has been for over 15 years. When we were discussing this story last night, she pointed out that the only breed (group of breeds, actually) that has never bitten her, nor even tried to bite her, nor acted aggressive at all while in her shop, has been pits. Allowing, of course, for statistically significant raw numbers -- she's also never been bitten by a Dogue de Bourdeux nor Irish Wolfhound, having only had one of each as a customer. She's handled hundreds of different individual pits. The greatest threat from them has been undocked tails -- they wag so furiously that it's like getting slapped across the thigh with a sjambok.
Leaving aside the dogs most likely to successfully break skin (Shih Tzus and Pomeranians), and just looking at dogs big enough to do serious damage, then Golden Retrievers, Collies, GSDs, Malinois (a highly trained Arkansas State Police K9, at that), Australian Shepherds, Malamutes, Siberian Huskies, Samoyeds, even lovable lugs like Great Pyrenees, have all tried to do mayhem to her, me, and/or employees. And some of them weren't just mad about the nail trim, some actually wanted to rip out throats.
Once again, let me point out that we've never owned any pit nor pit mix, and have no plans to. We're not defenders of the faith, just trying to speak the truth. (Speaking of, why isn't this dog being called a boxer?)
So... from a source that is biased neither towards nor against pits, there's some impartial data for you.

 about the undocked tail. I have been whipped more times than I can remember. It basically comes down to the fact that large dogs are the concern. Why they say pits are the bad ones, I will never know. Just seems to me no matter how big the dog the media will always come back and say its a pit and it isnt. This I think gets more viewers and concerns to provide drama I guess. I do feel that owner should have had those dogs on their leashes, and another pet peeve is the dang owners dropping off out here in the woods. It comes down to the owners just being responsible no matter the breed. Please though dont fuel the fire with the media bc chances are it isnt a pit.

  And the fact that we don't know makes it pretty silly to attempt to argue about whether it was justified or not.
