I know, but I don't know.

It is obviously my duty to deescalate & inhibit violence in my community when possible, while restricting people's avenues to tools that multiply the potential damage they can inflict.

This is why we have mental health care and regulations for buying explosives.

The best I could figure with my firearms at the time was selling them to the most responsible party possible, in my case it was gunsmiths. Recently some criminals attempted to break into their shop. Didn't get away with anything. So my choice already yielded measurable results in a way.

I'm not responsible people's heinous acts, but I am responsible for the environment people choose to act in.
