That isolated false positives created a lot of dead people, but even when you look at the statistics of how many dead people were killed by rich or poor people, the statistics are still overwhelmingly against poor people. Breivik and Lanza are exceptions that proof the rule. Furthermore, people purchasing semi-automatic weapons are not subjected to the scrutiny that I described. What I described is the process that you go through if you want to buy an automatic weapon. The high price of semi-automatic rifles such as AR-15's discourage use by people who would abuse them, but the even higher price of automatic weapons is even more effective. Only two people have been murdered with legally owned automatic weapons since the 1930s.
