It's definitely a push and pull; more are adopting it, but more are pushing back. The total amount is definitely still rising, though, but so is awareness.
There's Eugene and Springfield, OR; Cambridge, MA; a few in TX; Denver and Longmont, CO; Redmond, WA; Evanston and Oak Park, IL; etc.
I'm Oak Park (I helped write our ALPR General Order and the transparency reporting requirements that formed the case for killing the contract because it wasn't addressing real crime).
Oak Park is 4.7 square miles. All our surrounding munis have rolled out more ALPRs after we killed ours.
Further: because of the oversight we had over our ALPRs before, they weren't really doing anything, for something like 2 years. OPPD kept them around because they were handy for post-incident investigation. We effectively had to stop responding to alerts once our police oversight commission ran the numbers of what the stops were.
Which is to say: our "de-Flocking" was mostly cosmetic. We'd already basically shut the cameras down and cut all sharing out.
