Just another prick on the wall.

LONDON (AP) — The son of Pink Floyd guitarist David Gilmour has issued a public apology for climbing on top of one of Britain’s most important war memorials during violent student protests against rising university fees.

Charlie Gilmour says he wants to say sorry for the “terrible insult” to the thousands who died for the country. He says he did not realize the Cenotaph in central London commemorates Britain’s war dead. He added in a statement Friday that he was ashamed for his “moment of idiocy.”
