The owner let out a pit bull on the cop, made no attempt to control the dog. The cop may have interpreted this as an aggressive act by the dog's owner. We do not know why the cops were there to begin with. Leash laws apply.

The cop also had to worry about what the owners were doing while his attention was occupied by the dog's aggression.

I have dogs, and this dog was acting territorial.

The cop did all he could to retreat from the aggressive dog. Do tasers work on dogs, No telling how a pit bull would react?

I don't think that the cop should be bit before he has the right to defend himself!

I hope the owners went to jail for turning the dog loose on the cops...get a good dose of reality
