"The decision that has to be made was whether it was material, whether he knew he was lying under oath, whether he did it willfully. I think that's required of any prosecutor who is charged with an investigation of this"

This quote by Barbara Olson is describing the choice that a prosecutor must make when investigating a case. The prosecutor needs to decide if the evidence is material, if the accused understood they were lying under oath, and if they did it willfully. This is a crucial choice for a district attorney to make, as it will figure out the outcome of the case. It is the district attorney's obligation to make certain that the implicated is held responsible for their actions, and that justice is served. The prosecutor should be extensive in their investigation and ensure that all the realities are thought about before making a decision. This quote stresses the value of a district attorney's role in the justice system and the importance of making the best choice.
