I concede to “adjudicated”  being a legitimate qualifier.  I’m not sure, however, that the judicial system could handle the load.  Do you think that mentally challenged individuals should be allowed to possess weaponry?  Would they be capable of protecting their ownership of such?  The securing of such?  When it comes to implements that can kill as fast as a trigger finger can twitch, I believe in erring on the side of caution.

Rational reform could begin by requiring Universal Background Checks on all private, as well as licensed, transfer of weapons.  And I would not oppose reinstating the ban on military style, semi-automatic rifles and handguns.  (Yes, I know that statement, in your estimation, is proof of my own “mental illness”, yet, here I am, a gun owner.)
