The unrest in Ferguson, Missouri, is posing some new questions about law enforcement and the militarization of the police. Three teenagers from Georgia have decided to take the issue into their own hands. Caleb Christian, 14, and his two sisters — Ima, 16, and Asha, 15 — are about to roll out an app called "Five-O," which will let users document police abuse and join together as a community to problem-solve.

"We’ve been hearing about the negative instances in the news, for instance most recently the Michael Brown case, and we always talk about these issues with our parents," Ima Christian told Business Insider. "They always try to reinforce that we should focus on solutions. It's important to talk about the issues, but they try to make us focus on finding solutions. That made us think why don't we create an app to help us solve this problem."

Five-O lets users submit the details of any incident of police abuse and rate the specific officer. The app also has community boards for different counties so that users can communicate and plan responses to any difficulties with local police.
