Actually if you’re involuntarily committed you already lose your right to firearms (iirc there are steps to regain your rights, but they were not taken here). Red flag laws aren’t just bad from a “gun” standpoint, they’re bad because “innocent until proven guilty” gets thrown out the window and it becomes “guilty until you can prove you’re not crazy,” and proving the negative is always a more difficult position. It perverts our whole justice system, and while I have issues with other things doing the same thing (racism for example), adding more is imo not a good idea. I’d rather see them actually enforce the laws we already have which while more stringent than “my roomate seems unstable,” also would have prevented this. I mean the guy was commited (making him a prohibited purchaser) and displayed violent ideation to a degree that warrants keeping him for a little while, so they let him out, don’t take his current guns, and afaik fail to input his commital to NICs, that’s three things that already could and should have been done in this specific case red flag laws withstanding.

Gun restrictions aren’t enough though, the problem is people in general having access to guns.
