DENVER (AP) -- Colorado's attorney general decided against criminal charges Tuesday in nine alleged sexual assaults involving University of Colorado football players, blaming evidence concerns and the reluctance of women to go forward with the cases. Attorney General Ken Salazar, tapped as a special prosecutor by Gov. Bill Owens at the height of the recruiting scandal in February, said a "thorough review" by his task force resulted in a unanimous decision against charges. The decision was "based upon evidentiary considerations and/or the expressed wishes of some victims not to be subjected to the criminal justice process," Salazar said.
