Overkill to say the least. Isn't it odd, that an ordinary citizen has to defend their decision in a self defense situation, while the cops can almost ALWAYS justify the "shoot first ask questions later" mentality? Of course the dogs were a threat, thats what dogs do, warn and protect their owners. What about when the cops get the wrong address (like the situation in Atlanta, GA) and break down the door and killed a 92 year old woman? If a person defends themselves against that threat, even though it is the police, will the chief or sheriff declare that the homeowner was justified in shooting or LEO were justified in shooting? This nation is in serious trouble.
