With great respect to Mr. Greenspan, a very capable lawyer, like a lot of lawyers he's perhaps having difficulty getting his mind out of the legal context and into the parliamentary one. A witness does not have the option of not answering a question. But it is the case, and you've seen it yourself in the past, Mr. Chair, that a witness will have a lawyer who may seek to negotiate to go in camera because of whatever number of reasons, and the committee could do that. However, if the committee chose to not do that, the obligation rests with Mr. Schreiber to answer the questions that are put to him.
It is not the case, for the reasons I gave earlier...and which perhaps lawyers like Mr. Greenspan have a hard time believing, that the testimony given here would not be used elsewhere.
