Question

C

??In many businesses, computers have largely replaced paperwork, because they are fast, effective（高效的）, and do not make mistakes．As one banker said, “Unlike humans, computers never have a bad day.” And they are honest.

??Many banks advertise that their work is “untouched by human hands” and therefore safe from human attack. Computers have no reason to steal money. But they also have no sense, and the growing number of computer crimes (犯罪) shows they can be used to steal.

??Computer criminals don’t use guns. And even if they are caught, it is hard to punish them because there are no witness (證人) and often no proof (證據). A computer cannot remember who used it and simply does what it is told. The head teller(出納) 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 someone else’s account (帳目)．This man was caught only because he was a gambler (賭徒). When the police broke up a gambling group, his name was in the records.

??Some workers use the computer’s power to get revenge（報復）on bosses they consider unfair. Recently, a large company fired its computer assistant (助手) for reasons that were connected with her personal rather than her professional（職業(yè)的）life. She was given thirty days’ notice. In those thirty days, she got rid of all the company’s computerized records.

??Most computer criminals have been workers in low position. Now police wonder if this is “the tip of the iceberg（冰山）”. As one of the officials says, “I have a feeling that there are more crimes 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 how a computer works.”
