Again, let's pretend you're right. How do you bar someone from buying a gun because of mental health issues that are undiagnosed? Do we do a psych eval as part of purchasing a firearm? There's no part of common sense that allowed your local community to strip guns from you because then you'd be breaking a law by trying to steal from somebody and you'd probably get shot. We are talking about people with mental health issues that, in this scenario, have violent tendencies. I honestly see any way that declaring a mental health state of emergency can actually do anything to stop mass shootings unless it's also paired with stopping fun sales, strict red flag laws and legal confiscation of existing weapons.
Happy to hear an implementation plan that isn't just thoughts and prayers. Abbot (R, TX) says he's all in on mental health now, so let's see what that piece of sh comes up with.
