I think you're going to find that you're wrong about this, and that you're not going to get anywhere targeting Flock in particular, as opposed to the owners of Flock cameras. Consider that California has had multiple rounds of legislation about red light camera legislation, including new limitations on it, and all of those cameras are also from commercial providers collecting your PII. Your argument proves too much.

You're going to get a lot of cheerleading and support about this in venues like HN and Reddit, because you're narrowcasting to an audience already primed to be hyperconcerned about surveillance technology (I am too). I think you're going to find those attitudes do not in fact generalize to the public at large, and especially not to the legal system.

Best of luck either way. It'll be an interesting experience to write up, and I'm happy to read about the outcome, even if I do think it's highly predictable.
