On the contrary, many of these crimes, such as embezzlement of funds, the alteration of records, theft, vandalism, sabotage, and terrorism, can be committed without a computer. But with a computer,

4、 these offenses can be carried out more quickly and with less chance that the person responsible for the crime will be discovered. Computer crimes are on the rise and have been for the last twelve years. Just how much these computer crimes cost the American public is in dispute, but estimates range

5、from 3 billion to 5 billion annually. Even the FBI, which attempts to keep track of the growth or decline of all kinds of crimes, is unable to say precisely how large a loss is involved; however, it estimates that the average take from a company hit by computer crime is 600,000. A number of reasons

10、ion of more conventional crimes.Third, there are usually no witnesses to the computer crime, even though it may be taking place in a room filled with people.

11、nough people in management and law enforcement know enough about computer technology to prevent the crimes. Authorities have to be familiar with the computers capabilities within a given situation to guard against its misuses. In some large cities, such as Los Angeles, police departments have set up

14、 and investment firms are especially sensitive about revealing their vulnerabilities （脆弱性） because they rely heavily on customer trust.To avoid public attention, cautious companies will often settle cases of computer tampering out of court. And if cases do go to trial and the offenders are convicted

15、, they may be punished only by a fine or light sentence because the judge or jury isnt fully trained to understand the nature and seriousness of the crime.Not all companies are timid in apprehending computer criminals. For example, Connecticut General Life Insurance Company decided it had to get tou
