The founder of Blackwater USA deliberately caused the deaths of innocent civilians in a series of shootings in Iraq, attorneys for Iraqis suing the security contractor told a federal judge Friday…The attorneys singled out Erik Prince…for blame in the deaths of more than 20 Iraqis between 2005 and 2007. Six former Blackwater guards were criminally charged in 14 of the shootings, and family members and victims' estates sued Prince, Blackwater (now called Xe Services LLC) and a group of related companies…Attorneys for the former Blackwater company denied the allegations at the hearing, which was called to consider their motion to dismiss the lawsuit. [Judge T.S.] Ellis said he would issue a ruling "promptly.''
