A friend of mine once applied for a job with an unnamed federal agency.
The position involved analyzing video to determine if it had been
edited. So I know for a fact that they are concerned with this matter.

Given the things that can be done with video and still photos these days
I'm surprised any of it is acceptable "evidence". I'd guess that the
most critical thing would be the ability to track exactly where the
video media was from the time it was shot to the time it was presented,
as is the case with most evidence.

My friend was offered the job, but he turned it down due to insufficient
compensation.
