As mad as I am, I have a few questions as I know the dogs mean the world to the officers.

How many hours had he been working?
I'll bet a buck that he was over worked & his brain was fizzled.

Its still not a good excuse, BUT that just means there are more people to blame for this.

This kind of thing happens when people are over worked to the extream.. They mess up & its usually really bad!!! I feel sorry for the dog & for the officer, IF thats the case.
