Police state or policing the state?

The arrest of Tory shadow immigration minister Damian Green last week has sparked a ferocious debate. Whilst many claim that the police’s ‘Stalinist’ tactics are a step too far, others maintain that MPs shouldn’t be above the law. This scandal comes in the wake of several years of what many see as an increasingly authoritarian shift of power towards the state.

Should MPs have special privileges, or should they live by the same rules as the rest of us?
Have the police got too big for their boots?
What has happened to the political class’ old parliamentary ‘rules of the game’?
What does this issue mean for all of our liberties?
