I don't have the footage, and can't confirm handshake's statement about Portland, but I do feel as if I recalled hearing many airhorns being sounded as I watched live. It's been 6 months, and my memory's vague, but I feel like I remember thinking "that's weird there's so many airhorns" but I chalked it up as "maybe that's just what goes on at protests," which made sense in my mind at the time. I'm not the type to frequently watch "fight videos", so I'm ignorant.
That said, if one was to coordinate a cell of actors to FF at a large gathering, a coded use of airhorns blasts would probably be at the top of the effectiveness scale. In fact, I feel naive for not thinking of it when I was listening live.

This sounds like a good route to begin exploring.
