Answer:
Unfair treatment of teenagers by the police or authority figures can include excessive use of force, such as physical violence or use of pepper spray or tasers, even when the teenager is not posing a threat, or unnecessarily criminalizing adolescent behavior, such as arresting teens for minor offenses like truancy or curfew violations.
On the other hand, fair treatment of teenagers would involve treating them with respect and recognizing that their brains are still developing, and thus, they may make mistakes or act impulsively. Fair treatment could also involve diversion programs that aim to address the root causes of teen misbehavior, rather than simply punishing them.
