I've been attending gun shows for over 20 years and have yet to find fully automatic weapons, rocket-propelled grenade launchers or anything beyond one-round-per-trigger-pull available without a nosy (and expensive) Federal license.
The truly sad fact never reported is that the common Mexican citizens are deprived of effective firearms under their own laws - leaving the lawless, the corrupt and the government (and combinations of all three) the only ones armed. The drug cartels and their bought-off authorities would never had run roughshod over a citizenry empowered by a 2nd Amendment like ours.
These two dumbos are willingly subjugating our sacred constitutional right to bear arms.........to appease a foreign government.
