You are missing the point. It's not that Flock cameras are not intrusive (they are, I fully agree) but that your contract with the cell service company gives you some legal standing to claim you were injured. If your municipality erects flock cameras and you don't like them, you don't have standing in the same way because a) you are not a customer of flock with contractual rights that can be enforced, and b) elected officials are legally authroized to do things because they won political office via election. So unless you discover they were bribed by Flock or engaged in some other corrupt activity, you don't have the legal standing to complain about a policy outcome you dislike.
