I've bookmarked this UK announcement from July of 2018 about allowing citizens to upload dashcam footage to Police for later prosecution, and it seemed like foreshadowing of my own invented 'App' I'd been pitching for a few years:
Our app acts as a live-stream video recorder, and will allow user flagged video clips of law breaking to prosecute offenders seen, using the observable evidence collected during the video clip. It will stream constantly to the internet (with the local time, date, and GPS coordinates imprinted onto the video frame), to prevent users from manipulating the footage or submitting non-live or prepared footage. This will discourage the submission of 'baiting' and vigilante justice warriors trying to solicit child molesters and guilt them by public shaming. This behavior is questionable legally, and is not resounding 'proof' of wrongdoing - but a clear sign of a public want for participation in the whittling of criminals from our society.
We require all evidence be in the video clip: a continuous smooth shot of the license plate, driver, and any relevant street signs are expected with most moving violations (speeding, reckless driving, illegal U-turns, illegal stops, etc.)
