I think that it’s better that everyone collectively realize that video is no longer default-trustworthy in a widespread manner, if the alternative would have been the public finding out only after a long cycle of misuse by high-level actors and subsequent whistleblowing à la PRISM/Snowden.

however the forensic or semi-forensic tools should be given to people to help them verify the videos. On the other hand I suspect that these tools are not released so wrongdoers are not able to test their fakes against the tools (security by obscurity)
