As Ferguson continues to reel after Michael Brown’s death and the police threaten to shoot journalists and tear gas children, three badass teenage coders from Georgia have developed a timely mobile app to hold police accountable.

Five-O, created by siblings Ima, Asha, and Caleb Christian, allows users to detail their encounters with police officers and rate them on their professionalism. Anyone can check how their community stacks up and the information will be sent to law enforcement. “We’d like to know which regions in the US provide horrible law enforcement services as well as highlight the agencies that are highly rated by their citizens, explained senior Ima.” In addition to putting more power into the hands of citizens when interacting with law enforcement, we believe that highly rated police departments should be used as models for those that fail at providing quality law enforcement services.”

Though it sure as hell doesn’t feel like it much of the time, the police are supposed to “protect and serve” us — all of us. Law enforcement departments across the country should be thanking these high school students for helping them see if their officers are doing their jobs. The app is available for download starting today!
