The gun control controversy has resurfaced in the aftermath of two recent indiscriminate deadly shootings involving automatic weapons. In July 2012 a crazed gunman opened fire in a crowded Colorado movie theatre, killing 12. An even more horrific incident occurred in December 2012 when a mentally ill young man attacked a school in Connecticut, killing 26 people including 20 kindergarten children. In the wake of these incidents there has been a renewed call for an assault weapon ban, restricting access of mentally ill persons to such weaponry, and universal background checks. It remains to be seen whether these proposals will be enacted at the federal level as all gun control efforts have been fiercely opposed by organized gun owners.
