Bandits and Outlaws.

We have come a long way, since rooting for the good guys in the old Western and Cop movies.
Due mainly to media coverage and, post prominently, movies, the criminal lifestyle has been glamorised and popularised more and more, over the past 30 years.
Since the early Gangster Movies, like The Godfather (1972) and Scarface (1982) we have come to the point where the audience want the baddies to win, and even emulated their lifestyle.
In more modern times, the stereotypical Bad Guy has gone from a Mafia style Gangster, to more of a violent thug, mobster and football hooligan.
Guy Richie's movies, Lock Stock... (1998) and Snatch (2000), have attempted to combine both the retro and modern qualities. Combining The Gangster lifestyle, with blatant and gory violence, and some elements of comedy.
Now we have modern movies, like Football Factory(2004) and Green Street(2005), which are there simply to popularise the life of a football hooligan. Resulting in people buying the same brand clothing, Burberry & Stone Island, talking in the same accent and coining catchphrases and insults, and often copying the violence displayed in these movies.
These firms aren't stuff of fiction, most are adapted from true stories, and its easy to find websites dedicated to regional hooligans, like this website about midlans firms. http://www.football-hooligans.org/football-factories-midlands.html.
