Earlier quoted context omitted.
COPS like any TV show blurs people's faces unless they sign a release.
This is out of an abundance of caution, not necessarily because the law requires it. This explains it: https://www.quora.com/Does-the-Cops-TV-show-need-to-get-sign...
You asked what the difference was with the social media post vs. TV: The difference is that COPS, etc., don't want to be sued, so they get releases, because they realize that they could potentially be sued (and sometimes for good reason!) I sincerely doubt the person in the post signed a release from Amazon.
If you argue that it's technically legal, the OP wasn't specifically arguing that either.
> Even if one claims the video is fine (and I'd disagree), it's still a very very very bad idea for Amazon, or any large company, to be enforcing the law and conducting mass shaming via advertising.
