“Wanted by the FBI.” To the murderer, or the bank robber, these are the most frightening words in the world. When the criminal hears them，he knows that six thousand trained persons are after him.
Why should he be so afraid? There are thousands of cities and villages where he can hide，and forests and deserts, as well. Besides, he’s usually rich with stolen money.
Money can make it easier to hide. With money, the criminal can even pay a doctor to operate on his face and make him hard to recognize. But the criminals know that as public enemies, they can be found by the FBI no matter where they hide.
They know every trick the criminal knows and many more. If he makes just one mistake，they’ll get him. That’s why the man who is wanted can’t sleep. That’s why he becomes nervous, why he jumps at every sound.
The FBI began on May 10th, 1924. General Harlan Stone chose Edgar Hoover, a young lawyer, to head the new agency . “What we need is a wholly new kind of police force,” he said. “Criminals today are smart．They use stolen cars and even planes to make their gateways. They have learned to open any lock，using advanced technology. We can’t beat them with old methods. We have to train officers to work scientifically.”
Edgar Hoover quietly went ahead with his plans. He picked his men carefully. They had to be between the ages of twenty-five and thirty-five. He wanted only men with good manners and good character. When working as his officers, they would have to meet all kinds of people. Hoover wanted men who could handle a teacup as well as a gun. But the FBI cannot help in every police problem. It can look into only certain crimes against the government. Solving all other crimes is the duty of local police forces．
