A person with a bomb is a person who can consider using the bomb as an option. A gun trigger takes as much pressure to pull as most any child can muster. If a sucker-punch is accompanied by a knife, the effects are devastating despite the ease. Even in forms of martial-arts, nearly anybody using decent training methods over a few years time can give themselves the muscle memory abilities to fight. Our tools and skills training for diffusing violence seem far behind in development.
