I understand your point but I have a question. If you, as a private citizen, are walking down the street minding your own business, and somebodys dog comes running toward you, what do you do?
If an unknown dog is racing towards you in what looks like an attack, do you have the right to defend yourself using deadly force?
Why wouldn't a cop draw his taser, not his gun, when a strange dog approached? I would picture that as safer for everyone.
Should some woman start attacking you with kisses, caresses and aggressive body contact, would you shoot her?
A barking dog is different than an attacking dog.
I've lived a long time and have had many barking dogs come right up to me and I've never been bit.
Perhaps people like you should just stay home where it is safe.
