Laurie Berenson yesterday refused to condemn the MRTA rebel group that she’s accused of aiding. The presiding judge in her case concluded his fourth day of questioning of Laurie Berenson in her civilian trial by giving her a chance to speak out against the guerrillas, but Berenson said she was not going to condemn anybody. Berenson conceded she may have unwittingly aided the MRTA rebels, but maintained she is innocent of the charges against her.
