I don't believe the 2nd amendment mentions anything about permission or permits. I don't think anyone in the US needed permission or a permit to shoot the British back when they were trying to enslave America.

Who needs guns to take down military aircraft. You can take a landing helicopter down with steel cabe and some chain link fence. Are pipes, matches and nails illeagal in Europe if not you have guns.

numerous false statements in here as already pointed out. I would like to comment on a few things myself though. First, the "gun show loop hole" is a lie. The vast majority of sellers at a gunshow are dealers, therefore fall under the same rules and regs as a regular gun shop. Which means, a NICS background check, which depending on the state you live in, can also be eliminated. For example, in my state, a valid concealed carry permit allows you to bypass the background check requirement, as you have already passed one to obtain the permit. There is no, I repeat NO federal registration of firearms. When you purchase a firearm at a shop, they do not register it, unless you live in one of the soviet states of america like New York or California. As a matter of fact, in my state, they are not even allowed to keep a database of concealed carry permit holders, or gun owners. There is no state registration of any firearm, except the class 3 stuff that was already pointed out. Buying a gun online, going to a website like gunbroker.com, budsgunshop.com etc, they will only ship to an FFL dealer, which brings you right back to the NICS background check (depending on state laws for CCW holders). So as far as the little sensationalized piece that was reffered to by the OP, i call shenanigan, more anti gun lies to try and scare people.
