The polygraph machines are out at the CIA in a tough crackdown on leaks and leakers. First to go - fired last week for allegedly leaking word of secret American prisons abroad - was Mary McCarthy, 61, a veteran intelligence officer.
McCarthy worked more than twenty years for the CIA, including very senior positions at Langley and the White House. She knew the rules. But after Abu Ghraib, McCarthy allegedly leaked news of US secret "black site" counter-terrorism prisons.
Supporters call her a whistleblower and hero. Critics call her a villain. Her bosses have fired her, and the fallout is still coming.
Hear about the Mary McCarthy story, leaks, whistleblowers and the CIA.
