In the last three years, many communities across the state have adopted curfews for 16 and 17 year olds. The curfews were put in place to give parents and law enforcement a way to curb the growing problem of juvenile crime. The actual curfew ordinance for each city is almost identical, but the way each community has chosen to enforce the law varies greatly. Minnesota Public Radio's Gretchen Lehmann reports from St. Cloud, a city that just adopted it's teen curfew this month.
