Lea Artz, Head of Newsroom and Central Operations for Citizen, explains how the new app works. Citizen pushes an alert to your phone when there's an emergency in your area. Artz says Citizen could've helped the situation in Hawaii when a ballistic missile alert was accidentally triggered to anyone with a smartphone. Artz says Citizen "cuts through the noise." Citizen first launched as "Vigilante," but was quickly taken off the App Store after Apple believed it encouraged people to intervene in crimes being committed. Artz says Citizen has learned its lesson. Citizen is credited with keeping people safe and informed during the New York Tribeca terror attack in October. An elementary school principal says the app helped her make decisions and keep her students out of harm's way.
