Good cops don't operate on fear or cause deadly accidents, so yeah - bad cop. You ever been attacked by a dog? A shot of pepper spray is very effective. People even use high powered pepper spray to get 9 foot brown bears to leave them alone. If you're smart enough, you can stop an aggressive dog with voice and body language. From the sounds of it, this cop wasn't even attacked, he was
startled.
This specific cop is a complete moron and now someone is dead because of his stupidity, and the woman's husband and child got to witness their wife/mother killed for no reason other than the cop was scared of a dog. This is truly pathetic. I'm sure it's just an isolated incident though...

Cops are supposed to be "the authority." Cops have rights that citizens do not have, especially in regards to firearms. Cops are expected to be more responsible, more level headed, and more skilled with a deadly weapon than an average citizen. Cops are also expected to be trusted with public safety. The above are examples of BAD COPS.
