'Militia' Probe Included Undercover FBI Agent...

An undercover agent was part of the federal investigation of a Michigan-based Christian militia group that allegedly planned to spark an uprising against the government by killing police officers, court documents show.

Evidence presented to the grand jury in federal court in Detroit included photographs of Thomas William Piatek, one of nine people indicted Monday in connection with alleged criminal activities by the militia group, known as Hutaree, in southeastern Michigan.
