American Freedom Alliance Files Lawsuit Against Leading Science Center Over Intelligent Design Movie: Group Claims Cancellation of 'Darwin's Dilemma' Resulted from Organized Effort by Science Center to Suppress Discussion

LOS ANGELES, Nov. 24 -- American Freedom Alliance (AFA), a non-profit group, has filed a lawsuit in Los Angeles against a popular science museum for cancelling an event exploring the topic of Intelligent Design. The group says its free speech rights were violated when the California Science Center (CSC) abruptly reversed a decision to allow the showing of a pro-Intelligent Design documentary at the museum's IMAX Theater. The program was also scheduled to screen a pro-evolution film, but, the lawsuit alleges, museum officials were fearful of having Intelligent Design discussed in any context.
