4、ntify criminals? Experts now think computers can make it easier for the police to find people they want to question.At present, the system most widely used by the British police is called Photofit. Witnesses describe a suspect and then a picture is built up like a jigsaw, using five different sets o

5、f features. These are: hair, eyes, nose, mouth and chin. This system can be very useful in finding criminals, but only in one case out of twenty. Quite often, almost half the time, in fact, Photofit pictures are misleading. There are two reasons for this. Firstly, the picture may look nothing at all

6、 like the suspect. Secondly, the likeness may be so general that it is not at all helpful. And unfortunately, a bad likeness can lead to the arrest of an innocent person.Witnesses attitudes can influence their descriptions. In a recent experiment, a group of people was shown a picture of a man and t

7、old that he was a mass murderer. When asked to produce Photofit pictures of this man, they made pictures that showed a murderous-looking individual. But at the same time, a second group was shown the same picture and told that the same man was a lifeboat captain who had received a medal for bravery.

8、 When the second group produced Photofit pictures, these showed a man who was handsome and well-groomed.The police have another way of identifying criminals. Police records contain tens of thousands of photographs of people convicted of crimes. Witnesses can look through these in the hope of recogni

9、zing suspects; however, it has been discovered that a witness begins to forget the culprits features after spending a long time looking through these photographs.A computer system called FRAME （Face Retrieval and Matching Equipment） combines the best features of both methods. All the photographs on

10、record are put on the computer file. When a witness describes a suspect, the computer searches the file for photographs that fit the description. The witness is then presented with a small number of photographs to look through.Of course, this system, as it exists at present, will only help to identi

11、fy people whose photographs are already on police files. So now, experts have to work on the problem of getting accurate descriptions from witnesses. One thing they have discovered is that witnesses give better descriptions when they are encouraged to recall the scene of the crime. They do not need
