Bernard Jackson is a free man today, but he has many bitter memories. Jackson spent five years in prison after a jury wrongly convicted him of raping two women. At Jackson’s trial, although two witnesses testified that Jackson was with them in another location at the times of the crimes, he was convicted anyway. Why? The jury believed the testimony of.the two victims, who positively identified Jackson as the man who had attacked them. The court eventually freed Jackson after the police found the man who had really committed the crimes. Jackson was similar in appearance to the guilty man. The two women had made a mistake in identity. As a result, Jackson has lost five years of his life.
    The two women in this case were eyewitnesses. They clearly saw the man who attacked them, yet they mistakenly identified an innocent person. Similar incidents have occurred before. Eyewitnesses to other crimes have identified the wrong person in a police lineup or in photographs.
    Many factors influence the accuracy of eyewitness testimony. For instance, witnesses sometimes see photographs of several suspects before they try to identify the person they saw in a lineup of people. They can become confused by seeing many photographs of similar faces. The number of people in the lineup, and whether it is a live lineup or a photograph, may also affect a witness’s decision. People sometimes have difficulty identifying people of other races. The questions the police ask witnesses also have an effect on them.
