That doesn't refute my statement of the difference between preventive measures and the fact that treating mental health is something that occurs after. Furthermore, even if it did, the same would still apply to a trained martial artist that doesn't own gun who finds himself in a particular situation; so the two would cancel each other out.Preventing the accidents would be by treating the mental health issues. And therapy can be a lot more expensive then MA training depending on how frequently you go, insurance, and the level of therapy.
Either way, my original point stands: the measures necessary to prevent firearm mishaps require far less money and time than the cost of martial arts training.
