sentences:  Since adolescents are old enough to be left unsupervised, they have a higher risk of engaging in criminal behavior than young children do, which may increase the perceived need for constructive after-school programs, as Cook, Godfredson, and Na argue in their 2010 article in the journal "Crime and Justice".In the United States, interest in utilizing after-school programs for delinquency-prevention increased dramatically after research found that juvenile arrest rates peak between 2 p.m. and 6 p.m. on school days.By keeping students involved in school related activities, it lessens the chance for them to get involved in criminal activity or abuse drugs and alcohol.
