People die/kill themselves all the time without the help of the gun shows. The liberal bias is already evident in that article at the bottom where they reference "The gun show loophole" when 1.) This applies to private arms sales 2.) This does not apply to the licensed dealers who pay to have a table at the shows and must conduct a check for all fire arm sales 3.) There isn’t much control you can put on stopping people from killing themselves. Heck even people in guarded facilities on suicide watch manage to still kill themselves.
The best part about the crowds at gun shows is the fact that you can have 1k people gathered and a gun shot goes off and no one freaks out or panics. We just respond in a calm reasonable manner. That same thing happens with a bunch of hippie liberals and people will loose their minds, Crap themselves, and trample people in the panic.
I was at the Harrisburg show the other year and there was an accidental discharge. We just treated the guy for his wound, stabilized him till the medics got there and took him out on the stretcher.
