From his handle, this mook is an “auditor”, which is a social-media influencer genre. Despite the lofty and outraged claims that they’re merely defending rights (e.g. to video anyone, not just the cops, in public spaces) and educating people, what they do is basically a form of tr0lling for the lulz in the real world and then trying to translate that into followers on YouTube or TikTok (please do not reward this kind of attention -seeking behaviour with clicks or traffic).
While it’s sometimes fun to see them harassing cops who don’t know the law or bothering $cientologists outside their offices, they spend just as much time finding random people to wind up by ostentatiously (and legally) recording them from the pavement to see what happens.
