At this point, only a neighborhood watch, with baseball bats or some such or other arms as allowed, well enough padded/armored for the overwatch committee that will shortly be present at such gatherings (these aren't spontaneous, but are organized lootings), and ready to knock some heads will put a dent in this crap. The police won't do it, the stores will take the loss and leave. Only the neighborhood can impose the standards it wants to live with. Expect that to devolve into a shooting war.
Yep, I reckon that is saying that short of vigilante activity in opposition to this crap, nothing is going to change before the net election, and then it is a question of whether the looters outvote the honest residents.
In reality (because the police will be instructed to arrest any vigilantes for "taking the law into their own hands") and prosecution of those stopping this organized theft on the part of one dominant demographic is virtually guaranteed.
The unfortunate answer is to leave, let it rot, let the looters loot each other, and maybe build a fence to contain them.
