I haven't heard anything about this documentary "The U.S. vs. John Lennon" but it looks pretty cool from the trailer. The only problem with being such a powerful voice for peace and freedom is that it makes you a visible target for the forces of violence and oppression.
Some great quotes from the trailer:
"Our society is run by insane people for insane objectives, but I'm liable to be put away as insane for expressing them." - John Lennon
"Lennon represented Life, and Mr. Nixon & Mr. Bush represented Death."
