You are such an uninformed moron...from your very own link....
In both instances, Cho passed a federally-mandated background check conducted for Virginia gun dealers by the state police. Cho filled out paperwork for the instant check for the Walther at the Blacksburg pawn shop, waiting only ten minutes to be cleared, according to the shop's owner.
Yes I read that and didn't claim that he didn't pass basic BG checks at the time. I said screw Internet sales and include mental BG checks.
To be evaluated by whom? Are you qualified to know whether a person is a danger to himself and/or others? Medical professionals, even mental health professionals, have missed that diagnosis in their loved ones or among people they know well.
Should a person who was treated for depression that is now well controlled be denied access to a weapon of self defense? Should a person who needs treatment for other things classified as 'mental disorders' but that do not make that person a danger to himself or others be denied access to a weapon of self defense?
If we do not require that a person's doctor/patient privacy be violated in cases of abortion or buying a car or transgendering or purchasing a hunting knife, what justification is there in violating that privacy when it comes to buying a rifle or shotgun or handgun?
And even if that privacy was required to be waived to purchase a firearm, I'm pretty darn sure that 90% of those who do illegal violence with guns would have sailed through a mental exam with no problem whatsoever. Those on the public record with mental problems who were arrested/convicted of illegal activities would be the only ones that would show up.
