I will vote for the very unpopular opinion of HPs; though it's more like unfortunate victims and I most certainly sympathise with them.
I will not justify the riots and I wholeheartedly condemn them. But the job of keeping law and order lies with the police, not with vigilante justice. Shooting people is not a proportionate response to stealing.
While I would agree that ordinarily you shouldn't shoot a single thief that comes into your shop unarmed, a riot is a whole different situation. Seeing how some of these big box stores have been cleaned out, small businesses are at risk of being destroyed by this and I can't condemn it even if I am uneasy of vigilantes and citizens shooting citizens.
If the business is operating legally then they carry insurance.
The business is ruined whether it's looted or not because of the deep destruction to the community. Also, the Koreans killing black people was one of the causes of the riots in the first place.
