If you are adjudicated to be a danger to yourself or to others, you lose the right to purchase a firearm. You can appeal that adjudication by hiring a lawyer or a liberal one would be appointed for your case.
Are you saying that you believe the criminally insane have a right to purchase a firearm?
Are you saying criminally insane people can’t purchase a firearm now?. I was under the impression that criminals aren’t allowed to get them. The only people gun control laws will inconvenience will be the honest, law abiding citizens of this once sovereign nation. It will be very popular with the criminals,communist and/or liberals.
