I would do just what the Korean storekeepers did in LA.
Grab my AK and a couple thousand rounds and shoot every one who tried to break into my store or anyone elses store.
Let them eat lead.
I remember during the Cleveland riots some years back, a news article mentioned that only one white-owned store in a particular black neighborhood remained unscathed. This was when there were still real reporters, and he ran down the owner and asked if he paid protection money. Basically, the guy said, "in a way." and then went on to state that he hired two of the biggest, meanest-looking black guys he could find, armed them with shotguns, and placed them in front of his store.
One can debate as to whether the store wasn't ransacked because the looters thought it was owned by a "brother" or because they knew they'd get their ass shot off by a non-white and have no legal recourse.
