　　第三篇 Calculating Crime

　　When you think about math, you probably dont think about breaking the law, solving mysteries or finding criminals. But a mathematician in Maryland does, and he has come up with mathematical tools to help police find criminals.

　　People who solve crimes look for patterns that might reveal (揭示) the identity of the criminal. Its long been believed, for example, that criminals will break the law closer to where they live, simply because its easier to get around in their own neighborhood. If police see a pattern of robberies in a certain area, they may look for a suspect who lives near the crime scenes. So, the farther away from the area a crime takes place, the less likely it is that the same criminal did it.

　　But Mike OLeary, a mathematician at Towson University in Maryland, says that this kind of approach may be too simple. He says that police may get better clues to the location of an offenders home base by combining these patterns with a citys layout and historical crime records.

　　The records of past crimes contain geographical information and can reveal easy targets - that is, the kind of stores that might be less difficult to rob. Because these stores are along roads, the locations of past crimes contain information about where major streets and intersections (十字路口) are. OLeary is writing a new computer program that will quickly provide this kind of information for a given city. His program also includes information about the people who live in the city, and information about how a criminals patterns change with age. (Its been shown, for example, that the younger the criminal, the closer to home the crime.)
