It was up to the school officials to moderate the questions. Any fool knows that teens, especially boys, think about sex 90 percent of the time. A teacher should have stepped in and redirected the question to ask "Were you tortured?" or "Were you mistreated?" Frankly I think the pilot's answer was a good one and the entire thing should have been dropped. Perhaps the boy should have been counseled in proper deportment. He and the father may have an open relationship that allows them to talk about it, but I would bet that if the father had been raped he wouldn't want his son to ask him about it in front of 500 people.
The father's screwed up regardless. He defends the boy by saying all he was asking was a "fair, hardball question". WTF? Who does he think this POW is, some guy running for office?
