Truth on trial

In this episode the basic question was to whom is the attorney's first obligation to? the court, the public, or the client? The scenario in question is about the product space heater. The manufacterur doesn't want to put a safety switch on it becasue it would cost too much to do so and therefore, causing the products price to raise. There had been report on the product setting off fires and this was brought to the manufacturers attention. When manufacturers seeks counsel, the question becomes, does the lawyer have an obligation to reveil how dangerous the products may be? I believe he does not. Especially if the lawyer has not been retained by the manufacturers, so he would not be entitled to attorney-client confidentiality. When the case is taken to court, is it acceptable if the lawyers carefully frame their questions to make it seem that there is doubt in the other sides' case? I believe it is acceptable because not only is that their job, but both sides believe that they are correctively seeking justice. The lawyer basically has the obligation to introduce that truth which helps him and incourage the jury to dis-believe what he knows to be the truth if it helps the other side.
