The Seven Five is a brilliant documentary about NY police dept corruption in the 90s and 00s. Made me realise why in so many Hollywood movies there is the token 'bent copper', it was an actual reflection of reality rather than lazy token characters.

There are a lot of good European crime series on there, along the lines of 'bad thing happens in small town, all is not what it seems...'. But being European they come at it from a different angle to UK ones, which are more predictable as we are more familiar with the format.
