Let's think about that for a moment. Has that scenario stopped our current crop of legitimate criminals from owning weapons and using them in the commission of legitimate crimes?Why? They'll most likely have everyone disarmed by declaring everyone as a "prohibited person" via some trumped up farce of a crime, like saying you're a "domestic terrorist" because you criticized the goverment and are a public danger, or you yelled at your kid and that's "domestic violence".
I doubt it will stop people who being true law abiding citizens at 11:59:59pm and become felons at 12:01:01 just because some domestic enemy put ink to paper.
