What I don't understand is why the cop had to shoot the dog. I mean all he had to do was spray the dog with mace or fire OVER the dogs head. That would have def. scarred the dog away. Or at worse he could have hit the dog with the gun(would have been better then killing the poor thing). I mean there were other way of dealing with the situation other then killing the dog!!!!

He seems too quick to fire a gun. If that was a person that was rushing up to him, would he shoot them too? probably!!!
