Protecting the 9/11 "hijackers"

An account of the CIA's surveillance and protection from arrest of two alleged 9/11 hijackers. This story has often been told, but almost always – as in the recent TV series The Looming Tower – the most damning and incriminating facts are left out. These facts come, by the way, from US government official reports... For this episode especially, it's worth referring to the episode page, for a full list of sources.
