Dont breath, we might get a child killed if we do.
Does it save lives or does it kill lives? It depends which life you are talking about. It does kill/scare the bad guys and save the good guy in millions of encounters.
If the issue is saving children's lives, me think we should be well armed against those preying on them. Since legal gun owners are not terrorists, them infering that gun owners are seems to me that it is them who are the terrorists and child killers.
