An app designed to alert residents of New York City to crimes being committed has been pulled from the App Store, The Guardian reports. In a blog post about launching the Vigilante app, parent company Sp0n said it monitors crimes reported to 911 and alerts nearby users so they can get to safety or film crimes as they unfold. But the app didn’t last long on the App Store, with Apple citing concerns about its content, according to the app’s creator. While Sp0n claims “the closed system excludes the community while the open system informs and empowers citizens,” it’s easy to see how encouraging average citizens to get involved in investigating or stopping suspected crimes could be problematic. Apple declined to comment on why it removed the app, but a Sp0n spokeswoman said, “The team is working with Apple to resolve the issue and they are confident the app will be made available in the near future. Vigilante will introduce an Android version of the app in the upcoming weeks with plans to expand in additional cities later this year.”
