3rd party is a good way to go in some cases (i.e. for additional transparency) but I don't think it should **have** to be that way (I know you're not saying that, just putting it out there).  The overhead proposition is certainly something that should not be discounted.  The nice thing about reputation is that it is a function of time and thus harder to fake.  Its cost is something that we all experience at same rate and can easily understand.

Good point about eyewitness testimony. Its a different problem- successfully faking video isn't as easy many people think from a forensic point of view.  Even without applying something as "modern" as a blockchain methodology, there are reasonable things that can be done so that a video's providence can be independently confirmed.  However the mere suggestion that something is fake... or real... is often enough to cast doubt because it is an assertion in the affirmative (and not the double negative that I suggested earlier).

Except that the 3rd party could have the economies of scale to
demonstrate a reliable chain of custody.  Obviously simply the fact
that they're somebody else doesn't make them more trustworthy.

The 3rd party could use cameras that are tamper-proof that sign their
video.  The video could go into a repository that is protected.
Access to the repository could require participation of multiple
employees, following documented SOPs.  All their practices could be
audited by yet another trusted 3rd party.

A sole proprietor couldn't afford to do all that stuff, because it is
a ton of overhead if all they have are a few cameras in their store.
A 3rd party that manages cameras in 50k stores could easily afford to
make their process more robust.

Well, that is another vote in favor of 3rd parties doing this stuff,
because they actually could have a reputation.  If you record your own
security video chances are you'll never use it, but if you do use it
chances are you'll only use it once.  You'll have zero reputation.

Sure, I don't support bans on technology, and think they're pointless.
I was just commenting on the direction that all of this could take.
If video evidence becomes trivial to falsify then courts will either
require a ton of hurdles to submit it (which makes it less accessible
to people not hiring professionals), or courts will just pretend the
technology doesn't exist and lots of people get punished in courts for
things they didn't do.  The latter seems to be the approach courts
take to eyewitness testimony today (which is extremely unreliable, but
people go to jail on the basis of it every day).
