As long as there has been crime, there have been ways to solve it. One of the oldest methods is interrogation. A method in which police question people who might have committed the crime or might have the information about the crime. Interrogation can help the police establish the basic facts. But modern techniques for solving crimes include more complex, scientific methods.
Let me talk first about system, often called crime hotlines. In some cases, where law enforcement personal have difficulty in finding criminal, they turned to private citizens for help in solving the crime. This system allows people to make a phone call or access of website and give information to the police anonymously. This can often be effective when people are afraid to give information in public. Sometimes a family member may have committed a crime and another family member finally decides to call the police and give the information they have.
Second, fingerprinting. Each person’s fingerprint is unique. Ancient Chinese used fingerprint to sing legal papers. What a better way to identify an individual. Yet, it was only in the late 19th century that fingerprints were first used to identify criminals. A variety of scientific techniques make it possible for fingerprints to be lifted from most surfaces. Then they can be compared with the fingerprints the police have on file. A relatively new technique that crime fighters are now using is called psychological profiling. Criminal psychologists look at the crime and the way it was committed. Based on this information, they try to understand the personality and motivation of the person who committed the crime. Then they can focus on the search of people who can match the profile. In some cases, privet citizens are finding ways to solve crimes as well. With little knowledge of electronics, anyone can put a hidden camera in the home or office. In the 1990s, as an example, there were some cases where nannies were accused of abusing the children they were paid to care for. Hidden cameras were used to prove the nannies’ guilt. However, the technique is controversial, because it involves issues of privacy.
Finally, let me discuss DNA. Of the most recent crime techniques used, DNA is proving very effective. Each person with exceptionally identical siblings has a unique DNA coding system, so if criminals leave anything that can be tested at the scene of the crime, such as blood or hair, they can be identified. DNA was used to solve the crime first time in England in 1987. Since that time, it has become widely used and it was considered 99% accurate. DNA testing can also be used to prove the person who is innocent. Many prisoners have been released because the DNA evidence has proved that they did not commit the crime of which they were convicted.
