Three teenagers and a four-year-old were killed in a string of deadly shootings in Detroit during the summer. In response, Mayor Duggan and Police Chief Todd Bettison announced plans to ramp up enforcement of the city's curfew policy and more than double the penalty fees.

The city fines parents of teenagers who stay out past curfew hours without adult supervision. Officials say fines will encourage parents to step up and help reduce the violence, but experts argue this approach doesn't work and that it could cause more hardship for families.
