We have a prime example of the knee jerk defensive LEO reaction.
I would submit to you that it is a knee-jerk defensive reaction, period, and not LEO-specific. If a german shepherd mix (As this one seems to be, from the pictures) charges you, you better do one of two things:
Disable/dissuade it
-or-
Get out of the way
-or-
Pray for someone to help you, like the owner
Running with the assumptions-
STOP. I'll type it again for people who think that i'm exonerating anyone.
Running with the assumptions that the cop was charged by the dog, he did not realize that the dog was chained and/or he could not get to a position of safety fast enough, there is NOTHING wrong with him shooting the dog. If you were in that position, you'd do it, too, or you're an absolute idiot. Do you have any idea what a big dog can do to a human being? I do. I've seen a man's face half ripped off by a GSD. If you want to take a chance like that, be my guest. I'm not, and I don't expect any LE to do it, either.
Well, the LEO should not have been there, you say. Yes, he should have. He was investigating a crime. By the looks of it, this was the front yard of the house. He was walking up the driveway when it happened, assuming the media got it right (never a sure thing). Absent huge signs barring admittance, anyone (LE, CCW permit holder, you, me) could have been there legally, and he could have been there regardless of signage as long as he had reason to believe that someone he was pursuing was in the yard.
This is why so many of us are so distrustful. There seems to be a belief that the primary job of an officer is to "go home alive" regardless of who else is injured or whose rights are trampled.
Dogs are property. Legally, it is exactly the same as if he shot the guy's car. Dog owners and dog lovers, of whom I very firmly count myself one, might not like this, but that's the way it is. Should the owner be compensated for his loss, since he seemingly did nothing wrong? Absolutely. Should the officer be required to wait until the dog was chewing on his sensitive parts before he shot? Absolutely not. WOuld it have been nice if the officer had seen the chain and could have estimated its length and just stepped back? Of course. That is obviously the best outcome. However, try figuring out if an animal is restrained while being charged. It's a little more difficult than you might think.
Maybe those who feel this way should find another career.
It's hard enough to find qualified officers. Taking that attitude will ensure that no one with any sense volunteers to work for your PD ever again.

PS This post involves the reasonable assumptions that:
1. the officer was justified in being where he was
2. the officer could not see that the animal was chained -or- the officer saw that the animal was chained but could not get far enough away fast enough
3. the dog was actively charging the officer.
Change these facts, change my opinion.
