There's also "Essex Boys" with Sean Bean, I have always been fascinated with those Rettendon Rage murders, and those guys. They were a big deal down in Essex Tate in particular was a fearsome man, I think the film captures that.
I remember a few months ago on here there was a thread on the Rettendon murders and someone posted links to the pics of the 3 men dead from the Range Rover it was horrific to say the least!
It seems that only a few people believe that the right killers were caught for the crime. Lot of conspiracy theories.
