Trying to push back on this in my local community, two things I have found, below. Hopefully helpful to others.

1) I tried posting on Craigslist's "Community" section, in a simple attempt to reach out and connect with others who may be concerned. The posts were automatically blocked before even being published on the site. I tried multiple versions of this (i.e. with links and without, with pictures and without, etc.), from multiple accounts. Same result every time; the posted did not go through.

Obviously the word "Flock" would be easy to filter on, but if memory serves, even my very pared-down attempts that only used "surveillance" or "cameras" were blocked.

Why would Craigslist stop Flock-related posts from going through? The only answer I can think of is something along the lines of a National Security Letter. Certainly others here are much better informed about this realm than I am. Any other possibilities or perspectives, I'd be interested in hearinng.

I would also be interested in seeing what results other people get when they attempt to post on this issue to Craigslist.

2) So far my initial efforts to reach locally out via online contact channels to the City Council for more information have not been fruitful, and seem to be getting stonewalled (I'm not giving up yet though). In the meantime, I was able to do find the Flock contract, initial proposal, and other related documents using the City Council's agenda and minutes search tools. These search tools seem to vary by city, but may be worth looking into in your area.

I don't know where you live, but if you lived in Chicagoland the advice for how to engage on this would be easy: there are 1-4 (depending on your muni) Facebook groups where all the meaningful policy discussion happens. Hold your nose and log into Facebook and look.
