So, at least in my town, it looks a lot like violent protests of the sort you decry do help. Certainly nothing else has done as well.
In all these riot situations, it is portrayed as the poor sticking it to the rich, who presumably are using the police to oppress the poor. But I suspect that in reality it is mostly the poor becoming even more downtrodden by the criminal elements, and the rich remain unaffected. Perhaps the rich even profit a bit from what happens, such as politicians winning more government money to "help with all the troubles".

A little further down:
"Homicides in Baltimore are heavily concentrated within a small number of high-poverty neighborhoods."
So, my prima facie impression from these data points is the stand down has not benefitted the poor.
