I think it depends on how they use it. If you've been involved in an accident, due to the nature of litigation and laying blame and offences committed, I can see them seizing the camera. If they pull you and start trying to make you hand over footage then it's a different matter as it could end up as they want the footage to see if they can find an offence you may have committed. If that becomes the case then I'll get a hidden bulletcam if I want to volunteer evidence, and just use my Drift in tagging mode for general riding and normal mode purely for a vlog, then stop and turn it off/put it back to tag mode.
