Perhaps I haven't gotten a representative sample, but in 100% of the content I've seen from self-described "first amendment auditors", they're acting unpleasant and suspicious for absolutely no reason other than provoking a reaction. To me this seems like antisocial behavior that degrades rather than supports First Amendment protections. I consider myself a pretty strong First Amendment supporter, but if I routinely found strange men filming me as I walked down the street, I would support basically any legal change required to make them stop.
