    Historically, eyewitness accounts of a crime were a vital piece of evidence used in the prosecution of criminal offenses. Lineups were a method used where typically a group of individuals not involved in the crime along with the suspect whom is believed to be directly related to the crime are grouped together for the witness to review in the hopes to identify the suspect. This is accomplished in two ways, the first is simultaneous where several photos are grouped together at the same time (typically six) for the witness to review.

    404 Words  | 2 Pages

    In my opinion, the CSI effect is something that law enforcement may need to be concerned with. The CSI effect is where TV shows, such as, CSI, Crime Scene Investigation, Law & Order, Bones, and many other ones may alter the public’s perception about forensic science in criminal cases (Saferstein, 2015).

This type of mentality affects us more in the judicial system with criminal trials; whereas, some of the jurors would believe that law enforcement should have or
