After the San Bernadino shooting now all the politicians and talking heads are asking, "If you are not safe to fly, why would you be safe to buy a gun?" They're acting like it should be an automatic given that persons on the do not fly list should not be able to buy firearms. There's just a few problems... 1.) Many people who are on the do not fly list are not aware of it unless they attempt to fly. 2.) The do not fly list is fraught with errors. Many honest people are mistakenly on the list or have names resembling those who should be prevented from flying. 3.) Just how are firearm dealers going to be able to check the do not fly list? 4.) Um, gun shows? 5.) If they are going to buy guns for homicidal purposes, there is a plentiful supply of street guns. 6.) And the biggie: WE HAVE A CONSTITUTIONAL RIGHT TO BUY AND OWN FIREARMS!!! The government can't just add somebody to the do not fly list and then restrict their ability to purchase firearms. There are two solutions for that: 1.) Okay, pass legislation. Certain people with psychiatric history are not allowed to buy firearms. Felons cannot buy firearms (some exceptions). I still have a problem adding those on the do not fly list to this class of people who cannot buy firearms. 2.) Get a court order against each person on the do not fly list that removes their legal right to buy and own firearms. For US citizens I see grounds for a Constitutional counter-suit. For resident nationals, I'm not so sure they have any recourse. Does the 2nd Amendment apply to foreigners? And foreign nationals who cannot be located or are not in the country? Good luck serving them! But if nothing else, I see the problem of licensed gun dealers being able to access the do not fly list. I guess they pass on the vetting to some government organization so maybe they can check the do not fly list. But there's still illegal purchases, straw man purchases and gun shows. This is just another damned media circus that I cannot see going anywhere.
