Sexual assault pervades the military, but the Pentagon refuses to release records that fully document the problem and how it is handled, the American Civil Liberties Union and other groups said in a federal lawsuit that seeks access to the records. Tens of thousands of service members have reported some form of sexual assault, harassment or trauma in the past decade, according to the lawsuit filed [on December 13] in New Haven against the departments of Defense and Veterans Affairs. "The government's refusal to even take the first step of providing comprehensive and accurate information about the sexual trauma inflicted upon our women and men in uniform ... is all too telling," said Anuradha Bhagwati, a former Marine captain. The government prosecutes 8 percent of military sex offenders, while 40 percent of civilian sex offenders are prosecuted. The lawsuit contends sexual assaults are nearly twice as common within military ranks as in civilian society, and surveys show that nearly one in three women report being sexually assaulted during their time in the military. About 80 percent of unwanted or threatening sexual acts are not reported, according to the lawsuit. Victims who report abuse to their superiors often face social isolation, retribution and counteraccusations, the lawsuit says.
