Nothing stolen...looks like some sort of test. Or maybe someone is race baiting to get people to make comments in the media.
Maybe this was training camp for Black Expo here in Indiana this week?
Or produce a few useful idiot "martyrs" laying dead in some shopping aisles. "They wuz jes goin' 'bout they bizness". Sooner or later somebody threatened in one of these incidents is going to lay down fire. Useful idiots and cannon fodder.
“Nothing was stolen” Are you really sure?
