You both have me on this point. Shall we amend it that to "criminally insane" as found in a court of law, and/or as to be found so incompetent as to be under the care of a legally appointed guardian?
Here's the real problem with 'regulating' sales of weapons. It gives the state the ability to, in effect, prohibit person to person transfers, as per existing CA law. -- I cannot legally give my adult grandson a gun. It must be a registered transaction thru a licensed dealer.
This violates a number of my constitutional rights to property [see 14th], as well as the 2nd.
Of course that is insane.
This thread's point is about purchasing firearms which I think can fall under the commerce clause.
