AAQ
“So, these states DO have background checks except the gun shows?”
I believe license firearm dealers are federally mandated to perform background checks, this applies in all states
“Did the latest murderer buy his gun at the gun show? ”
No
“Are gun shows a significant source of guns used in crime?”
Yes. Though exact data is hard to vcme by as no records are kept (whcih is exactly the problem)
Bu several reports indicate that this is a source of guns used in crime see aTF report from 2000 Following the Gun: Enforcing Federal Laws against Firearms Traffickers. found that 30% of guns used in crimes were bought through gun shows. his was the second most common source of guns used by criminals (first place were those bought through a strawman which accounted for ~ 40%)
not sure what that rat is that you smelled.
Please let me know if you have any other questions.
