I wish I had a link, but it isn't on our local paper's site yet.
Long story short: A friend of a friend of mine let his pit bull out to use the bathroom this morning and it took off on him. A short while after he heard some yelping sounds, and when he tracked it down, he found that his pit bull had killed a GSD. Normally, this would result in a fine, maybe some minor jail time, and the death of his dog.
The catch: the GSD was a K9 officer. The man, at this point, has been told that he is looking at a minimum of Assaulting an officer, but the police force here wants to pursue manslaughter charges.
Yes, I think the guy was a bonehead for letting his pit bull out without a leash, but I think manslaughter is a bit excessive for the death of another dog.
