Taking away guns does not solve the reason for which they become used by some people.

The cost, such as politically and time & energy to lobby, would be better spent making the social net better, or add more mental health services that target more people, and to prevent people from getting to a state of destitution (and fall into crime).

I generally agree. However, I’d say “both/and” is reasonable. Yes, let’s avoid a society filled with destitution—the market actually works better when you take care of people. Also, let’s stop the proliferation of murder machines. A conservative court should recognize that there is not an individual right to bear arms except by the convention of the court. The second amendment supports well-regulated militias. The current court is not conservative so much as cynical.

“A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed”
