1) Societies (all around the world) tend to be more racially driven than we like to admit. It's really easy to ignore the suffering of a group of people if you are readily able to distance yourself from them. Race plays a significant role in this in many places.
2) Develop systems that are structurally uncorruptable and uninfluencable as best as they can be, by having significant separations of power by design. There must be no incentive for those with the power to audit to be influenced by those they're auditing.
3) Probably many, scarily enough. Corruption runs deep in many societies that tend not to be considered corrupt.
In this case, I like the idea that the officers should be sentenced to prison at some level proportionate to the amount of corruption they were responsible for. The wrongly imprisoned should be released, and the State responsible for implementing the auditing controls against these officers should be forced to provide the wrongly imprisoned the average (for a given value of average) wage, or a multiple thereof to account for additional damages, for the entirety of the time they were wrongfully convicted and imprisoned for. That way, there's a personal incentive not to be corrupt in that if you get caught you are heavily personally punished for said corruption, and there's a strucutral incentive to implement effective anti-corruption controls as the state is then responsible for those that represent it.

Oh kind of like The Constitution, for example? Obviously that hasn't worked out too well in the long term, what with the US being a burgeoning police state and all.
But if "we" write a new and more sternly worded piece of paper that says "rulers can't mistreat their subjects", that should work, right?
Try again without the facetiousness. I don't mean like a piece of paper saying 'thou shalt'. I mean by implementing systems where, by design, the decisionmakers over roles that police each other have no way to influence one another. For example, those who are in charge of policing the police shouldn't also be in charge of working with the police on policing other people. I don't mean auditors, I mean those who then receive the information from internal audits and are responsible for making judgements based on it.
In reality, "the separation of powers" was just a bullshit PR-distraction, meant to give us a false sense of security, to alleviate the nagging subconscious awareness that the idea that we live in a system that benefits us just makes no sense whatsoever.
Regardless of how parts of the government are ostensibly "separated" or "firewalled", they're still all part of the same overall organization: the government.
There's no way to arrange an all-encompassing "authority of coercion" in a way that benefits the people being coerced. Another way to look at it is that forcefully taking people's money does not benefit whoever's money is taken. It benefits the takers.
The exploiters need the masses of the exploited to be blind to the exploitation, because otherwise it would come to an end, and that's why we find the idea of "the separation of powers" floating around, along with "the social contract" and "consent of the governed" and so on.
For 1), even modern liberal people still have racist-like prejudices which are not intrinsically different. We're led to believe it's wrong to discriminate based on race so we just transfer our discrimination to some other classification. Blacks are OK, but not if they're from Africa. Indians are OK but not if they're from India. Whites are OK but not if they're from Syria, Irish are OK but not if they're from Ireland. That is, racism has morphed into nationalism, which is widely acceptable so we feel it's OK.
Similarly, homophobia has morphed into "pedophobia". We can't hate gays anymore but we're plenty virulent at hating pedophiles. Just the same emotions transferred to another group.
Inside, most of us are still basically the same bigoted people, but we've restructured our bigotry to fit the popular modern values.
