The FBI arrested nine members of a group called Hutaree this past weekend. According to officials, the group planned to wage an all-out war to bring down the U.S. government.  Authorities said Hutaree's initial plan was to kill a law enforcement official and then plant IEDs to kill more officials who attended the funeral. If you're thinking this is a militant Islamist group, you're dead wrong: Hutaree is a Christian militia group based in Michigan. Hutaree's philosophy, stated on their website, reads, in part, that they are "preparing for the end time battles."
