The crowd of people slowly marching while getting shot and teargassed or the protesters. Those in the liquor store are the looters. Pretty simple.
If firing indescriminantly into a crowd makes it hard to tell these groups apart it sounds like the police tactics need work.
Oh well, the liquor store is getting looted. Sucks that you can't deal with that because there are protests because you are murdering black people. Fix the bigger problem before worrying about property.
