I wish you the best of luck in addressing that symptom in a society where such bans aren’t commonly-supported, where the law isn’t conducive to such, where there’s such an incredible established base of ownership, and where “fuck the government and/or police” is the prevailing theme.

By all means, when you’ve discovered some way of meaningfully and feaaibly surmounting these, share with the class. You’ll be the first to have done so.

Meanwhile, the rest of us will focus on the root issues - the pressures toward violence - rather than only caring someone decided to use a rifle to when finally pushed to the brink.
