Read the following pasage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.
From 1940 to 1956, a man called George Metesky set off bombs in places like movie theatres and train stations all over New York City. A psychiatrist named James A. Brussel was called in by the police to help. He used crime scene photos and others from the bomber to profile the criminal doing the bombings. He assured the police that the man was middle-aged, unmarried, and a skilled mechanic from Connecticut.
This was an example of criminal profiling. Profiling is used when a criminal's identity is unknown. Based on profiling, a psychological sketch of the person is created. This sketch helps the police more easily find him or her. It Is an essential tool for the police trying to solve major crimes. Profiling has been used for a long time to help the police.
Profilers are not police officers. They are experts who create criminal profiles for the police. They use the crime scene evidence and psychology to write about the suspect. They can't tell who the person is, but they can tell the police what kind of person to look for. To be a profiler, one needs a degree in psychology, criminal justice, or behavioral science. Profilers sometimes work in police departments and sometimes they are independent workers.
Profiling is especially effective in cases of repeated crimes, like serial killers. The profile tells the police what the killer may act like. It also tells the police what kind of person the killer may target next and where it might happen. That way, the police can prevent further crimes. Profilers can learn a lot about a criminal's habits from the evidence they leave behind.
All of this is impressive, but not everyone agrees with profiling. Some say it's just a guessing game. It may not always work, but profiling methods have improved over time. Today's profilers are much better than previous profilers. They can create better profiles thanks to decades of knowledge and experience. Even if their information isn't perfect, it's still a great help to the police.
