That is not reasonable to me. The idea is to keep innocent folks from getting shot. If I have to get government permission to buy a gun there is no right to keep and bear arms. There is government granted privilege to buy a gun, but they can kick in my door and take it if some leftists decides I am "mentally ill".
No sale.
If we really did have a right to Keep (own) and Bear (carry around) a gun the whackos would only get off a shot or two before getting scragged. Like the subway scene in Predator 2. Stop looking to Mommy government to "protect" you. Ain't gonna happen.
The Leftist-tyranny fans want to incrementally make it more and more like you need their permission to exercise your commonsense civil right of self-defense.
Once they’ve achieved that nirvana of control that permission will be withdrawn.
You can bank on it if we let them get away with it.
You are already being vetted (getting permission) to buy a gun by having to go thru the NICS process. That doesn’t stop a private sale, of course. At this time.
Do we want to stop truly insane people, or not? If we do, then something along these lines is reasonable. I have an uncle who was diagnosed at a young age with schizophrenia. He was, at times, violent. To my knowledge he never had or tried to get a gun. I would not be happy to hear that he did.
The ACLU fought to close down all the insane asylums. What stops the former residents from doing some major harm?
And I know there is no perfect safety in this world. But some things can be done that won’t be more devastating than what we already experience.
