In this Thursday Dec. 9, 2010 photo, Charlie Gilmour, the son of Pink Floyd guitarist David Gilmour, holds a flag with the word ‘revolution’ on it as he marches along Horse Guards Road, as Horse Guards Parade can been on the right, during a demonstration in central London against government plans to triple tuition fees. Charlie Gilmour has issued a public apology for climbing on top of one of Britain’s most important war memorials and trying to rig a British flag during the violent student protests against rising university fees. He added in a statement Friday Dec. 10, 2010 that he was ashamed for his ‘moment of idiocy’ and he did not realize the Cenotaph in central London commemorates Britain’s war dead.
