In recent weeks police have been seen to arbitrarily stop and search young people outside the Taking Liberties exhibition at the British Library (slogan: "In some countries you wouldn't have the right to visit this exhibition about your rights").
The police excuse, we are told, was that it was "half term" (are kids now so bored in their holidays that they resort to terrorism?).
But the Metropolitan Police entry in the Irony Awards has since been eclipsed by their colleagues in Bristol. Paul Saville, a student, was arrested for chalking on a pavement: "Liberty: the right to question. The right to ask: 'Are we free?'"
"The whole reason I was writing in chalk was because I wanted to get my message across without causing lasting damage," Saville told the Daily Telegraph. "I was merely highlighting the point that we are losing civil liberties in the UK."
He has since been charged with criminal damage.
