This is an old one, but you can never hound the practitioners of idle factoids enough. The Telegraph carried this letter on Saturday:
Sir - How right Boris Johnson is (Comment, November 29) in appealing for all fair-minded Muslims to speak out against the extremists of their faith: but don't hold your breath.
Didn't Edmund Burke say: "All that is necessary for the triumph of evil is that good men do nothing"?

The answer to the question is no, Edmund Burke did not, and I'm surprised the Telegraph let it through.
