Joe. My. God.: ACLU Issues App To Record Cops
The ACLU of New Jersey has launched a smartphone app that will secretly record your encounters with the police.
The ACLU’s Alexander Shalom said the app is easy to use. “There’s really only three buttons that the user needs to deal with,” Shalom said. “There’s a know your rights button that educates the citizen about their rights when encountering police on the street, in a car, in their home or when they’re going to be placed under arrest, and there’s a button to record audio and a button to record video.” The app lets users record audio and video discretely with a stealth mode that hides the fact that the recording is happening. Shalom said officers would also have a harder time deleting the recorded incidents.
The app can also send your recording directly to the ACLU.
