Answer to Question 1
According to research studies, more intensive police patrols of crime hot spots, devoting resources to arresting serious repeat offenders and police efforts to seize guns carried in public are effective in reducing crime. Computers and other modern technologies enable police forces to locate and arrest the relatively small number of people who commit large numbers of robberies and burglaries. Putting these people in jail has a much bigger impact on the crime problem than imprisoning someone who commits a crime only occasionally.
Answer to Question 2
It may be that young people are more likely to be arrested for committing a crime than older people. Or it may be that older people are actually less likely to engage in criminal activity. Young people's higher rates of criminal conduct may be due to opportunity and physical capability: Young people are more likely to commit visible offenses, such as property crimes and robbery, than hidden crimes such as embezzlement, price fixing, or corporate malfeasance. In addition, young people have the strength, agility, and stamina to commit crimes such as burglary and robbery.
