What's a "crazy" person and who get's to define that as well as check the box on the magical federal database of "crazy" people who can no longer purchase or possess any and all firearms?

One can have a mental illness but not be "crazy". Most on the Darkside are living proof of that.

You saying you want your doctor to determine if you have a mental illness, and if so, to put you in a database that removes your right to own, use, and purchase a firearm?

Why are you only including "anti personnel assault weapons"? Do other firearms not kill? I'm pretty certain every single firearm in my safe can kill just as easily as the one sitting next to it, regardless of shape, form, color, caliber, etc.

I don't see this Pandora's Box getting opened any time soon, not to mention your post seems ill thought out and possibly derived from what I'd consider a response to border on "crazy".
