You have to see it from the cops perspective. The dog looks half dead & suffering horrible. All the cop was doing was putting it out of its pain. Rob did the same thing to a deer. He was driving his armoured truck & hit a deer. The deer's hips were broken so she couldn't walk. Rob said she was crying, so he called the cops to ask if it was ok to shot the deer to put it out of her horrible pain & they said yes, so Rob shot the deer twice in the head.

& I see no difference between a dog & a deer in pain.. the cop probly thought it wasn't gonna live anyway.. I would have done the same thing.
