If you fancy a bit of rough after the latest installment of Little Dorrit (8.30pm, BBC1), here's a profile of gangster James "Whitey" Bulger and his cohorts. Organised crime is as old as mankind but urban life in the United States, particularly in the last one hundred years, seems to create conditions that bring this particular human behaviour to a new level. The Irish have played a major role with their own secret societies and gangs in the US. This second series of the very popular documentary follows the story of the Irish Mob in America from the 1950's to the present day. This programme featurs the story of Pat Nee, who was born in Rosmuc in Connemara but grew up on the tough streets of Southie in Boston. In an exclusive interview, Nee recounts how he fell into a life of crime and charts his rise to the top of the Boston Mob. For years Nee ran the Southie rackets alongside the notorious 'Whitey' Bulger before concentrating his energies on running guns to the IRA.
