Capitol Hill, Washington -- Emotions ran high during a hearing in the House on youth boot camps.

Lawmakers and witnesses compared the treatment of teens in the camps to the kind of torture faced by prisoners at Iraq's Abu Ghraib prison.

Greg Kutz has led an investigation into youth residential programs for the Government Accountability Office. He says the programs use deceptive marketing practices when trying to persuade parents of troubled youngsters to enter the programs.

Kutz testified that investigators uncovered cases in which a pit bull was trained to bite students and where teens had bags placed over their heads and nooses slipped around their necks.

A visibly angry Congressman George Miller says "it's hard to believe that people would do this to somebody else's child." He has introduced legislation to prevent such abuses and boost oversight of boot camps.
