Computer criminals(罪犯)don't use guns. And even if they are caught, it is hard to punish them because there is often no proof. A computer cannot remember who used it. It simply does what it is told. The head teller at a New York City bank used a computer to steal more than one and a half billion dollars in just four years. No one noticed this because he moved the money from one account(账户)to another. Each time a person he had robbed questioned the balance in his account, the teller said it was a computer mistake, then replaced the missing money from someone else’s account. This man was caught only because he was a gambler(赌徒).

Some workers use the computer’s power to punish their bosses they consider unfair. Recently, a large company fired its computer record assistant for reasons that were connected with her personal life rather than her job. She was given thirty days notice. In those thirty days, she robbed out all the company’s computerized records.

Most computer criminals have been common workers. Now police wonder if this is “the tip of iceberg”. As one official says, “I have the feeling that there is more crime out there than we are catching. What we are seeing now is all so poorly done. I wonder what the real experts are doing the ones who really know a computer works. ”
