The whole thing is dumb. Of course the NRA are hypocrites... was there ever any doubt they weren't?
But on the flip side allowing people to carry guns to event with the Vice President at it... give me a break. Its like when Republican voters like my mom complain about Hillary and celebrities having armed security or Al Gore flying in a jet. It's the dumbest form of argument that for whatever reason international press has decided is some sort of deep thought nobody ever came up with except the Parkland survivors.
