Sometimes, people need to control their emotion. Surely you would be pissed off if you ran a business and your store got looted, windows smashed, building burned, etc. People put work into that shyt.
Let me first answer your question. If it was my business, I would be upset.
Then let me say this. Your view is myopic as it pertains to this situation. This is the consequence of centuries of oppression in America.
This is the consequence of white people seeing black people prosper in Greenwood in 1921 and being so outraged, that they massacred Black Americans and dropped bombs on the town. Don't even think anyone got arrested for it.
fukking with people and pushing them too far for too long has consequences. People hit back and strike out, and there will be collateral damage. It's a pity, but it is what it is.
