I have a simple, clear approach: if a person is too dangerous to be allowed to have a gun, then he is too dangerous to be free on the streets.
Courts should be able to convict people of being "a danger to themselves or others"-level of crazy, and put away. Until that point, they have full rights, including 2nd Amendment rights.
“...Courts should be able to convict people of being “a danger to themselves or others”-level of crazy, and put away....”
And even THAT is a slippery slope. A free society is risky, but worth it, IMHO. What you suggest will end up being done, no doubt, but mass shootings by lunatics is but a small, yet overly publicized problem. The biggest murder problem in this country, with and without firearms, is with the inner city black population. Until the cause of this pathetic situation is throttled we will not bring the nation’s overall homicide rates to what should actually be expected of such an advanced society.
Black lives DO matter, and as a nation we need to address this problem of SUPER-high abortion and homicide rates in the inner city black population. In a fair analysis of world wide crime statistics, the ownership of firearms, especially the misnomered “assault weapons”, is statistically unmentionable as a factor in death rates.
Addressing anything else before this abysmal factor is no more than lip service toward this public safety issue.
