This is an extremely important point! “More than 75,000 prosecutions every year are based entirely on the recollections of others. While perjury is a felony, the overwhelming majority of eyewitness errors aren’t conscious or intentional. Rather, they’re the inevitable side effects of the remembering process.” Most of us don’t know or believe that eyewitness accounts and identification are inherently unreliable! This type of evidence HAS to be tested. This is why we have trials.
