26、deral money, increase in young males and other population changes. Crime rates in the United States have been dropping for a number of years. Rates of violent crime have fallen to their lowest levels since the 1970s. President Bush noted this in his declaration in April for National Crime Victims Ri

27、ghts Week. But this week, a report from the Federal Bureau of Investigation offered new evidence that violent crime may be on the rise. Early numbers for the first half of the year show violent crime was up three and seven-tenths percent over the same period last year. The F.B.I. reported earlier th

The information in the F.B.I. report comes from more than eleven thousand law enforcement agencies. Researchers from the Justice Department

32、are studying a number of cities to look for reasons why violent crime is up nationally. Experts suggest a number of possible reasons. These include too many illegal guns and not enough law enforcement officers on the streets of American cities. Also blamed are reductions in federal money for local l

Now they are expected to fight terrorism in addition to traditional crime. At the federal level, the F.B.I. and other agencies that often help local officers investigate cri

34、mes have seen their duties change as well.But other researchers believe an increase in young males and other population changes have played a part in the rise in violent crime.
