| Abstract: | Should witnesses truthfully reveal all information or present the evidence in such a way as to support one side of the dispute? The ability of a witness to distort evidence at some cost in support of the prosecution in a criminal case is considered. It is shown that when distorting the evidence is more difficult, the number of convictions and the accuracy of the decisions improve. When distorting evidence is less costly, the jury must set high standards for conviction, which leads to fewer convictions. |
