Influencing Court Cases Critics of the CSI. effect argue that jurors have unrealistic expectations and expect a case to be quickly solved based on forensic evidence. The series, they say. has given jurors, lawyers. and the general public a simplistic education on analyzing evidence. Many judges are now seeing cases where lawyers for the prosecution or defense rely more heavily on forensic c s I. technicians than before. They expect the technicians to quickly process blood. ngerprint, or DNA evidence in their favor. DNA samples like blood or hair evidence now dominate a larger part of court cases. This is in contrast to previous cases where motive and opportunity to commit a crime were the main focus. This puts added pressure on forensic technicians. Never before has such a popular TV show had such an important effect on the justice system.
