The Omnibus Crime bill made us safer

but it did fill up the prisons.

The Omnibus Crime Bill was passed in 1993 providing stiffer sentences and more money for crime control. Firearm-related homicides declined 39%, from 18,253 in 1993 to 11,101 in 2011. Nonfatal firearm crimes declined 69%, from 1.5 million victimizations in 1993 to 467,300 victimizations in 2011. In 2010, the rate of firearm homicide for blacks was 14.6 per 100,000, compared to 1.9 for whites, a decline of 51% for blacks and 48% for whites.

If I can find these BJS stats, then why can't the media? What will decrease mass shootings are armed security guards in schools and malls.
