Nice thought, but unfortunatly in this day and age if you want to own a gun, that is enough to clasify you as a nutjob.
We're talking about the law, not Rosie O'Donnell's wet dreams, okay?
18 USC 922 (d) It shall be unlawful for any person to sell or otherwise dispose of any firearm or ammunition to any person knowing or having reasonable cause to believe that such person -
(4) has been adjudicated as a mental defective or has been committed to any mental institution;
(g) It shall be unlawful for any person -
(4) who has been adjudicated as a mental defective or who has been committed to a mental institution;
to ship or transport in interstate or foreign commerce, or possess in or affecting commerce, any firearm or ammunition; or to receive any firearm or ammunition which has been shipped or transported in interstate or foreign commerce.
When they start trying to pass laws defining the desire to own, carry, or operate firearms as a "mental defect," then I'll be actually worried.
