Russian person here. Why do you think paying the police more would reduce corruption? Highly paid government officials in Russia are just as corrupt.
Here in the US, police are paid quite well and retire with a nice pension. They also win a free-paid vacation if they kill an unarmed civilian. They call it "suspended with pay".
Despite all that, they also taser the elderly and teens half their size: https://www.google.com/search?q=police+taser+elderly++&o... I read a blog for priv. prop. anarchists and they never run out of stories like those.
