(AP) - ADDS INFORMATION THAT ONE OF THE PEOPLE SHOWN IS NOT GOING ON TRIAL --This combo of eight photos provided by the U.S. Marshals Service on Monday March 29, 2010 shows from top left, David Brian Stone Sr., 44, of Clayton, Mich,; David Brian Stone Jr. of Adrian, Mich,; Jacob Ward, 33, of Huron, Ohio; Tina Mae Stone and bottom row from left, Michael David Meeks, 40, of Manchester, Mich,; Kristopher T. Sickles, 27, of Sandusky, Ohio; Joshua John Clough, 28, of Blissfield, Mich.; and Thomas William Piatek, 46, of Whiting, Ind., suspects tied to Hutaree, a Christian militia. Jury selection is getting under way in Detroit federal court Tuesday, Feb. 7, 2012, nearly two years after the dramatic arrest of people who authorities say belonged to a southern Michigan militia with a goal of rebelling against the government. The trial is expected to last weeks. It involves seven of the nine people charged with belonging to a group called Hutaree. The government says they conspired to try to kill a police officer and plotted further strikes. No one was ever attacked, and the defendants say they're being prosecuted for saying stupid things. Joshua Clough, bottom row second from right, is the only defendant to make a deal with prosecutors and could be called as a witness to testify against the Hutaree. (AP Photo/U.S. Marshall)
