Indeed. A gun show is like a flea market for guns. You are buying not from a gun shop but from some random individual. Obviously there are no background checks performed. Just like if you found it in the newspaper classified ads.<quoted text>So it isn't a gun show loophole but a private seller loophole. He/she/it may not even know what the gun show loophole really means but quite the talking point.
Not sure what kind of laws would really be effective in such private transactions.
