Interestingly, statistics show that the number of gun deaths (in fact, all violent deaths) has actually gone down in the past 20 to 30 years in the U.S. There is one area, however, in which it has gone up, and that is the incidences of one shooter with mass killings (Columbine, Virginia Tech, Aurora, Sandy Hook). The perpetrators were all mentally disturbed (if not outright insane) individuals. Apparently, the Sandy Hook shooter snapped because he thought his mother was going to have him committed. If we need to blame someone, let's go to those liberals in the 80's who felt it was unfair to keep people committed against their will, or to force them to stay on their meds.
