Sure.
But, as I think more about it, it occurs to me that one need not have a genuine ability to arrest or convict. If it works in the reader's state, he could always just record the repeated refusals to leave, then hike down to the nearest magistrate and swear out a warrant. Even if the magistrate refuses, the cops will sit up and take notice of the attempt. Especially when you include the attempt in a formal written complaint to internal affairs along with the recording.
Often, just making yourself a bureaucratic pain-in-the-butt, will deter abuse. It also makes them recognize, "Oh, jeez. We gotta be careful with this one. He's willing to fight back." I strongly suspect that "fight back" reputation is the main reason OCers are generally left alone by cops. I think there are lots of cops who routinely violated 4A rights on other people as a matter of course in their daily activities. Then one fine day one of them bangs into an OCer, starts to pull his usual rights-violating tactics, and suddenly discovers those tactics don't work because the OCer knows his rights, and is willing to make noise about it by way of formal written complaint or lawsuit. I think the same can apply to any situation with cops, not just OC.
