Josh Meyer, co-author with Terry McDermott of The Hunt for KSM, visits the International Spy Museum to talk about the decade-long FBI and CIA effort to capture Khalid Sheikh Mohammed. Meyer discusses the repeated failed attempts to find the evil genius who had plotted to kill the Pope and President Clinton and explode a dozen planes over the Pacific Ocean, all before masterminding the 9/11 attacks. Finally, hear how the US finally grabbed KSM as a result of the interrogation of another terrorist, Abu Zubaydah.
