A judge on Thursday ordered the release of a former Marine who was detained for psychiatric evaluation after posting strident anti-government messages on Facebook. Prince George County Circuit Judge W. Allan Sharrett said at the end of a one-hour hearing that the involuntary commitment order issued by a magistrate against Brandon J. Raub was invalid because it contained no allegation or basis to hold him, according to the head of a civil liberties organization that represented the 26-year-old veteran.
