Is sentencing for rioters 'over the top'?

As the conviction and sentencing of people involved in the criminal damage and looting last week continues, questions are being asked as to whether the punishments fit the crime.

Two men have received four-year prison sentences after they used Facebook to try, unsuccessfully, to orchestrate serious disorder in Northwich and Warrington during the riots.

Jordan Blackshaw and Perry Sutcliffe, were sentenced as a deterrent to others, according to the judge.

Newsnight's Kirsty Wark asked Tory MP Margot James and John Cooper QC whether the sentencing was an over-reaction.
