According to the Colorado Bureau of Investigation (CBI), major crimes across Colorado have dropped 6.1 percent from 2007 to 2008. This is the third straight annual decline in crime in Colorado. Major crimes that were reported in this study include homicides, rape, robbery, aggravated assault, assault, burglary, larceny and auto theft.
In addition, during this period, CBI has reported that auto thefts have dropped 22.1 percent. This decrease in auto theft seems to be part of a nationwide trend and is attributed to the difficulty in stealing newer cars because of better theft protection.
Another reason for a drop in crime rates is due to police being able to collect DNA during their investigations of all crimes. This includes burglaries and auto thefts. Trace DNA is collected and checked against state and federal databases. Because of this added resource, police can solve crimes faster and keep repeated offenders off the streets.
However, criminologists caution that crimes with economic motive such as burglary, theft, robbery and auto theft, could increase with a deepening recession.
