When Jason Mattera got a chance to launch an unplanned interview with U2's lead singer Bono, he probably couldn't believe his luck. And he had certainly done his homework, preparing to catch the Irish singer, famous for his charity work, in a web of hypocrisy and lies. Mattera is practically panting with joy at the prospect of "nailing" Bono.
Over the years, Mattera has specialized in this type of journalism (oh dear, where do you put the quotation marks in a sentence like that?) with such people as vice-president Biden (O'Biden, to Palin fans), to Chris Rock and others.
