With that exception, in most cases, I think it is more a matter of protected children rather than child witnesses or children related to witnesses. All sorts of complications can come up.
For instance, the accused can be the father of the child whose mother is a witness. You can see the types of complications that may ensue. That has actually happened before. Those are almost always isolated cases. I don't think that is a serious problem.
However, in terms of the disclosure of information, we have to remember that 12-, 15- or 16-year-olds can put people in danger, most likely unintentionally, because they don't understand the scope of their actions. However, that can still happen. So we have to pay attention to all that.
I wouldn't make the assumption that the people managing the program do so foolishly, without paying attention to the needs of the children. However, we know so little about the children in protection programs that it is hard to say.
For instance, I had an opportunity to ask in person whether this type of situation occurred in international courts, such as the International Criminal Court. I was told that, to the knowledge of prosecutors, children have never been witnesses. However, we are often dealing with children of witnesses who, as a result, need protection.
