A federal judge has dismissed a lawsuit accusing the FBI of civil liberties violations by using an informant to spy on several California mosques. Former informant Craig Monteilh has acknowledged posing as a Muslim convert to collect the personal information of mosque members and even record their meetings and conversations. But on Tuesday, U.S. District Judge Cormac Carney threw out the case, saying it would risk disclosing government secrets. Two groups representing the plaintiffs — the American Civil Liberties Union and the Council on American-Islamic Relations — say they plan to appeal.
