1. Yelling at a dog you do not know to do anything is almost always pointless. The dog was probably trying to get to it's family (pack).
2. Dogs don't "circle... to attack". They aren't indians from a 50's serial. Dogs charge straight in and low. They grab the closest thing to them on their target.
3. If he wanted to protect himself, and his fellow officers, then the car doors should have been shut to prevent the dogs from exiting in the first place.
This officer needs to be removed from the force and this unit needs to be trained by some K-9 guys in how to handle dogs when making an arrest.
Absolutely. At the very minimum, police should be taught to identify breeds. This cop didn't have a clue.
