Controversial Film "How to Blow Up a Pipeline" Sparks Warnings and Debate.

The FBI has issued a warning that the fictional film "How to Blow Up a Pipeline" could inspire real-life terrorist attacks on energy infrastructure. The alert was one of at least 35 missives from at least 23 separate federal and state entities issuing dire warnings about a commercial film's threat to the nation's fossil-fuel infrastructure. However, civil-liberties advocates and other experts say telling police nationwide that moviegoers could turn into terrorists might have serious and damaging consequences.
