Ok, for one example, after the 2008 housing market drop, banks bought the debt from other banks intentionally writing bad loans, which they then resold to third parties. This buying up of the debt of the banks that collapsed during this time lead to banks pushing families out of their homes, many of which were paid-up, but the lending institution behind them had failed, in order to resell the property later, when the market prices had recovered, or use the land for other developments. This was enforced by the police. Bankers did not go around forcing people out of their houses, the police did it at their behest.

Another is laws created specifically to punish people for being homeless. Laws like not being able to camp anywhere near a place they might be able to get themselves out of homelessness, e.g. a place with jobs, and other resources, not some place way out in the forest. These are also only effective because the police use violence to enforce them. Anti-solicitation laws fall into this category. Police often don't realize that (speaking for my country) they are not constitutional at the federal level. Police departments that know about this tell their cops to do it anyway because it's not like homeless people will likely be able to sue them.

A third is the enforcement of petty traffic fines. Things like window tint, or minor violations in situations where the safety concern isn't present. These fines are, often, the brunt of how they fund themselves. Petty violations, like tint, are also used to go on fishing expeditions, so they can either wrack-up more fines, or make an arrest, even if that means intentionally escalating the situation, lying about what happened, and giving false testimony in court. More arrests, more convictions, equals more money for the police, and the legal industry as a whole. If you work with, or around, police, like I have, you will hear them discuss things like testilying. Bouncing ideas off of each other as to how they can make bad arrests, and use illegal levels of force, while having a technicality to maintain their immunity, e.g. screaming quit resisting, while in a position where they know cameras can't really see what is happening. This is just the tip of this iceberg, I would need thousands, upon thousands, of words to detail all the shit I have heard police say, and see police do.

I can go on, but I think I have made my point.
