CHICAGO (AP) — The latest act of mass violence to hit the U.S. has focused attention on Highland Park’s 2013 ban on semi-automatic weapons and large-capacity magazines. The clampdown survived a legal challenge that ended at the U.S. Supreme Court’s doorstep in 2015 when justices declined to hear the case. Police say a gunman used a high powered weapon “similar to an AR-15″ when he opened fire on an Independence Day parade Monday in the northern Chicago suburb, killing seven people and wounding more than 30.
