Human societies have relied on eye-witness testimony since Cain and Abel. Sure, you can study it and discover that humans are unreliable (film at 11!) but it's silly to think that we are going to have trials and testimony and leave out eye witnesses. What's important about our trial system and juries-of-peers is that the average person feels the system is doing its best to find the truth so that it's not necessary to form vigilantes. Our system is overall pretty good, better than asking all the people who show up at a crime scene or later to protest.
