Video is B.S. and speculation, the gun show "loophole" occurs either on premise or off premise, depending on the show and whos putting it on
If a private transfer occurs off-site, then it's like any other transfer and the gun show has no actual part.
If it occurs on-site in a state that does not classify gun shows as the grounds of an FFL (private transfers are prohibited on the grounds of an FFL), then the gun show still does not play into it, since it is a private transfer that happens to be taking place at a gun show.
It is you who is speculating and spreading misinformation. Do educate yourself. Perhaps go to a gun show or gun store in the states and find out for yourself how the gun laws work.
Here's Steve Crowder doing a hidden camera video asking gun stores and a gun show specifically named by Obama to break the law.
