imagine an app that is sort of like a panic button. You get pulled over, you open the app and hit the button which then (depending on your preferences), starts recording/streaming video and audio, locks the phone, and maybe starts recording accelerometer/gps data, etc.
It would need to be thoroughly developed/tested before actually it could be ethically recommended.
What do you think? Good idea? Bad idea? unfeasible? Already existing?
Here in America, they might also shoot the camera, you know, in self defense.
