Well we have 14TiB of financial documents archived on our kit. There is no way we even would consider such compression!!!

The whole thing is dangerous and wholly illogical.

This is akin to a crappy crime flick where someone hits the "enhance!" button on a CCTV still a few times and gets to see the dirt on the guy's teeth.

In this case, the computer decides the guy is female and has no teeth.

IIRC when security cameras moved from individual frame compression algorithms like M-JPEG to modern codecs which could sometimes replace small movement in background with still image if there is a bigger change in foreground there were news reports about some problems with investigations.
