People have already discovered a cop that was undercover purposefully starting some of the looting to incite the protesters.
I hate people who keep closing their eyes and yell omg, looters are bad, look at these bad actors. Half the time, looters have been pushed to that point because either cops were beating them with baton sticks or hitting them to tear gas, or instigated from undercover police agents like this. Is looting bad? Yeah, but guess what, until the BIGGER problem which is our fucked up police force goes through an entire overhaul, looting is not the worst issue. People who think looting is worse than what our militarized police force are doing now should check their own priorities and thinking.
