thats the whole point, sherlock.......people buy tons of guns with no background check and then get to pass them on to anyone they like....I'm sure very few are stolen.......but they re-sell them or give them to someone and they often wind up in the inner city.....
keep trying
Holy crap you're so woefully ignorant on the subject it's not even funny the majority of guns used in criminal activity are not bought at gun shows they are stolen from law abiding citizens
Do some freaking research
