I watched a Russian film called "Na igre" from 2009. The main premise of the film is a sci-fi scenario, but everything else seems to be supposed to be set in modern times. It's set in Nizhny Novgorod.

What's very disturbing, is
1) There are several very bad criminal organisations around, and this seems to be taken for granted.
3) When bad things happen, the protagonists don't call the police because they don't trust them and think they may be in league with some of the criminals.
4) The protagonists all have the view that you can't have a good life doing a normal office job, but instead, being a gangster in a "protection" scheme is the way to make money...

The level of criminality and police corruption that was depicted, is unthinkable in a Western European country. You couldn't use that in a "realistic" film, because everyone knows that's not how things are.
But in this Russian film it's part of the everyday life for the protagonists.

I was left wondering if the bad depiction of the police in this film reflected how things really are in Russia, and how people think of the police. Is the trust for the police really that low?

I have no personal experience of the police in Russia but I have read some complaints, both from Russians and tourists to Russia, that the traffic police are corrupt and accept bribes as routine.
