There is an attempt to mitigate certain risks like in the case of a challenge for cause. When there is reason to believe that a perspective juror may be biased, questions are asked in that regard. He will be asked, for instance, about knowledge of newspaper articles or media reports. It is possible, in asking these questions—usually the jury is present, the sworn jury and the other candidates in the room—for the person being questioned to provide an answer which may be very prejudicial to the accused. He could say, for instance, that he has already got an opinion on the accused's guilt because he heard such and such a thing on television. That is what we are trying to avoid.
