Power does corrupt. But more than that, it attracts authoritarians who live for power abuse. And the top authoritarians are the ones who hire low-status authoritarian thugs and give them a uniform and (more or less) free reign to bully, abuse, and intimidate.
Police abuse starts at the top of the culture, not the bottom. Replacing the people on the ground will do nothing without also replacing the people who use police power for their own ends.
That won't happen without political and economic change. A traditional redistribution of wealth and power won't be enough. The problem needs a new political system with checks and balances that provide strong immunity to authoritarian capture by narcissists and sociopaths of all labels and persuasions.
