Well, it is clear that at least one of the people in that confrontation is a horrible person. We don't really know which one. (Though, some people here are happy to let their prejudices influence them)
Maybe a more productive conversation might be to ask under what circumstances it is acceptable to post images and videos captured in public of people in unflattering conditions and situations.
Many of the people posting about that video are concerned that it is dangerous to unleash the wrath of public scrutiny on people. Some of them don't feel that it is okay for a person to, for example, get fired from their job "just because they said the N-word."
Legally, in the US, if you are captured in public, you are fair game unless you have a reasonable expectation of privacy. So, for example, Upskirts aren't allowed but the make model and identifying attributes of your automobile and the exterior of your home visible from a common public access way are definitely allowed. Now in some European countries, it is illegal to distribute images taken of un-consenting citizens to the public which caused a problem for Google Street View, but not in the US.
So I don't think the video posted by the guy was illegal, but what about the ethics?
Assuming for the moment that the guy did experience some unwarranted rude behavior from the woman, is it okay to retaliate by posting a video of her reacting badly to a confrontation? Let's keep in mind that the public attention placed on her could result in several horrible consequences that might dwarf the bad behavior motivating the retaliation and also that some bad behavior including criminal behavior shouldn't ever be allowed to be hidden from the public.
