This is human EVIL (which is often in the guise of ignorance) at it's epitome.

This is video from a police car's dash-cam that shows Tennessee State Troopers shooting a North Carolina family's dog (around 3:03 in the video). It happened while the family was returning from their vacation in Nashville. Police say they stopped them because they "matched the description" in a robbery that had just occurred (they were actually incident). The officer who shot the dog (Eric Hall) hasn't been punished for the episode; he has only been reassigned to "administrative duties". The Tennessee Department of Safety issued an apology here: http://tennessee.gov/safety/newsrelea...

Here is the account of what happened from the point-of-view of Eric Hall: "I yelled at the dog to 'get back' but it attempted to circle me to attack, so I felt that I had no other option but to protect myself."

Here is the account of what happened from the point-of-view of the family: "My dog then came out of the car and ran towards the officer with the shotgun and flashlight. We started yelling to please let us get him, don't shoot, he was only barking at the flashlight and jumping at the light. My son plays with him using a flashlight. This is when my dog was murdered."
