Reply #3: took him 25 years,

running gun shows and,ostensibly, make his fortune from them, before he decides that they are flawed?

He retired before he came to this realization? Sounds insincere as hell to me..

"The background check is not just a thing that's done on the individual it's also running the background history on the gun.

Never had a NICS check yet that even listed the gun to be purchased.

Pope proposed a new law that would require background checks on any gun sale at gun shows, even transactions between private parties.

Sounds to me like this guy is "proposing" a quite a bit more then just background checks at gun shows.
Perhaps Tennessee has it's own background check in addition to the NICS check that all non private sales at gun shows have to go through.
The article could be a bit more clear on this.
