Look at the local political structure in place in all these cities! What is the party affiliation of the Mayor? The police chief? Those two positions alone have a ton of institutional power to resolve these issues, yet theses places have had issues for decades despite that party having a near stranglehold on power.

Who the fuck voted them in and kept voting them back despite their failures to fix the issues? The fucking Russians?

No, it was the community. They got the local government and thus police that they voted for.
