Two shootings, one in Charleston and another in Detroit. Funny the media is only on a feeding frenzy on the former. MOTUS does the  compare and contrast:
1. On the evening of June 17, 2015, a mass shooting took place at Emanuel African Methodist Episcopal Church in downtown Charleston, South Carolina. Nine people were shot and killed; a tenth person was shot and survived. South Carolina law mandates that Emanuel African Methodist Episcopal Church and all churches in South Carolina are “Gun-Free Zones”. 
2. On the morning of June 21, 2015, as about 20 people were dining at Pete’s Grill and Coney Island on the Detroit’s east side, a man walked in, pulled out a gun and said he was robbing the place. The armed robber was pointing the gun at everyone, telling them all to get down and not move, while demanding the workers “get to the register.” Instead of getting the register, an armed employee fatally shot the perpetrator. Pete’s Coney Island and all restaurants in Michigan are NOT “Gun-Free Zones” butt rather they’re “Self-Defense Zones ” and permit Concealed Pistol License holders to legally carry firearms.
