British Gangster Films - Do They Have An Effect On Their Audiences?

I have decided to research into some famous British gang films which may or may not have an effect on their audiences..
I am going to look at 'Lock Stock and Two Smoking Barrels', 'The Krays' and 'Reservoir Dogs'. By conducting more research into these films, I will see if the media have made attempts at saying that one of the films caused certain criminals to commit the crimes they commit.
