Oh, most definitely. And honestly I still think anyone who calls themselves a first amendment auditor is more likely than not a little out of whack with regards to the norms of society and the law.

I believe every example I’ve seen roughly boils down to:
“I’m going to stand here and film this elementary school to see if anyone oppresses me by saying I can’t”
Cop: “everything okay here sir?”.
"This is public property and I can film here if I want. You have no right to tell me not to!”.
Cop: “that’s alright, I only asked if everything was okay. We got some reports about strange behavior and that you were making people uncomfortable so I came to check up on things”.
“Well now you know that everything’s fine, no one has anything to be concerned about because it’s perfectly legal, and you can run along now. Good bye.”.
Cop: “alright, well it might be nice if you considered moving along, since you’re making people uncomfortable. Just a thought. Bye.”.
Title: “1st amendment patriot schools cop on meaning of the law”.

Cops are assholes, but those guys invariably share videos of the least objectionable behavior to illustrate that.
