Journalist Christopher Bollyn was assaulted by the police and had his arm broken, when he began to report on the links between Israel and 9/11. He escaped to Sweden where he lives in exile, but his expertise on Israel and 9/11 (he speaks Hebrew) is still one of the most respected on the planet.
I want to make it clear that after years of study I'm still unsure of the full range of methodologies used that day.
Actually it doesn't really matter, and the people who fuel those arguments are often cognitive infiltrators to use a contemporary expression. However we do know the criminal architects behind the crime even though they had lots of help by their friends in the CIA, DoJ, Pentagon and Congress.
These are Netanyahu, Dov Zackheim, Michael Chertoff, Larry Silverstein, Jules & Jeremy Kroll, Frank Lowy, Philip Zelikow, Paul Wolfowitz, Richard Perle, Douglas Feith, Jack Abramoff and a special shout out to the gentiles Dick Cheney, Donald Rumsfeld and the odious L. Paul Bremmer.
Update: Christopher is now back in the US though not in his home state.
