Also in July, the Detroit City Council voted to parents will face if their children violate curfew to US$250 for a first offense and $500 for a second offense. Before the vote, parents were , an amount that hadn't been changed for decades.

I am a and in the School of Criminal Justice at Michigan State University, where I study affects children and families.

While the curfew and fines are designed to deter crime by encouraging parents to keep a closer eye on their kids, research suggests it could instead worsen economic hardship and existing inequities among vulnerable families.

I believe that understanding youth crime through the lens of adolescent development offers communities more promising ways forward.

Parents play key role

Parents matter. Evidence shows strong reduces youth crime. , who their friends are and where they are spending their time are more likely to keep them out of criminal or dangerous situations.

The fact that parents have such a strong influence over delinquency makes the question of legal parental responsibility particularly important.

In the United States, parents may be held legally responsible for their children's actions through civil and—in rare cases such as the —. Crumbley's parents were found guilty of involuntary manslaughter tied to a 2021 school shooting carried out by their son.

Fines like the ones imposed on Detroit parents for their children's curfew violations are usually —behaviors that are illegal only because of a child's status as a minor. Examples include consistently missing school, running away, underage drinking and curfew violations. The goal of curfews is to prevent delinquency late in the evening, although a systemic review of relevant research suggests that .

Do parental responsibility laws work?

Despite widespread use, there's to support the idea that parental responsibility laws deter delinquency. Instead, they may produce unintended harms.

Three challenges limit their effectiveness.

First, my own research finds that parents, particularly those from , often of juvenile justice laws and processes. Parents cannot prevent or respond to violations they do not fully understand.

Second, fining parents for curfew violations may put extra financial pressure on families that are already struggling. These fines are based on the idea that parents aren't supervising their children well enough. In reality, even may not be able to stop a teenager from breaking curfew if they're working late or juggling multiple jobs. Families that can least afford these fines are hit the hardest, making their . On top of that, fines can between parents and kids, and add to the household.

Why do kids engage in crime?

Finding appropriate solutions to youth crime necessitates understanding why youth engage in crime in the first place.

Compared to adults, young people are less able to weigh long-term consequences, resist peer pressure, regulate emotions and control impulses. At the same time, their brains are especially sensitive to novelty and social rewards. This combination means that, in emotionally charged situations, teens may engage in risky or even harmful behavior despite .

What policies show promise?

Adolescents' brains are still maturing, making them prone to impulsivity, sensation-seeking, and reward-driven behavior. While these tendencies can lead to harmful behavior such as crime, they can also take such as pushing limits in sports or getting on stage in the school play.

Community-based programs that offer safe, supportive spaces can redirect youths' natural risk-taking into positive outlets. , such as the arts, sports and clubs, foster belonging and purpose while reducing isolation and reliance on antisocial peers.
