I would love for one of those idiot explain what the 'Gun show loop hole' is? I have bought several guns from the gun shows in VA and I fill out the same paper work that I do in the gun stores. If you have an FFL and sale a gun then you have to do the FFL paper work.
As soon as you do universal back ground check on people buying guns, then someone will have the aclu suing the government for labeling them as crazy. Everyone knows that a crazy person doesn't need a gun to commit a crime. If they want to harm someone then they will find a way.
I don't know the stats on how many people are killed every year with AR, AK style rifles, but this how been a hot button for a while. I bet it is a very small percentage of the overall gun related murders.
