W: Hi, Frank! I just saw a program on TV that said that juvenile crime was increasing. And I want to ask your opinion because I know you work with a lot of young people.
M: Well, first...I think the media worsens the problem, and so does the school system. Where I live, we have thousands of security guards in the schools, and metal detectors, too.

[单项选择] Computer Crime A computer crime is generally defined as one that involves the use of computers and software for illegal purposes. This doesn’’t mean that all the crimes are new types of crime. 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.
