Whenever I see local police collaborating with ICE, or taking anti-immigrant stances themselves, I think about this line of argument from Police and the Empire City about how police in the early 1900s celebrated the rise of deportation as a possible solution for solving xenophobic crime panics.

If you want a book about the try-fail-try-again adventures of a very racist and xenophobic NYPD and how they adapted to mass immigration in New York in the early 20th century, may I suggest Police and the Empire City.

This CEO and Ring in general talks constantly about how Ring "makes communities safer" but they never answer the question: How? You put up cameras..and then what?
His answer is honestly baffling: Cameras are supposedly deterrents (they're not) and something something flood lights.

He FUMBLES the question he gets asked about how AI is going to integrate into Ring to keep people safe. The interviewer gives a softball about what happens if neighborhood knowledge and communication like one might see through a HOA or private security is used in a "dystopian way". Gibberish:

It *is* possible to get cross-jurisdictional and multi-police department Slack chats out of departments via public records requests. Here's a glimpse at the Chicago-area police Slack chat with people responding with the 👀 emoji to the news that there's been an ICE-involved shooting.

Because of this.

even said that he likes beautiful women as much as I do, and many of them are on the younger side. No doubt about it --
Jeffrey enjoys his social life."

🚨 We wrote about Flock rolling out "distress detection" that monitored human voices on their gunshot detection devices & asked how it was lawful under eavesdropping laws.
Now, they've changed the ad to replace a "SCREAMING" alert with a "DISTRESS" alert. See below:

I cover in my book that in the era between 1900-1925, police around the world worked collaboratively to offset the image of the dumb fist-fighting officer and tried to make it something that *appeared* professional, standardized, scientific, and objective.

Newspapers pre-WWI era in the US are *filled* with moral concerns that police were illiterate, uneducated, and mindless thugs hell-bent on using their discretion to beat up people they didn't like. SOME of this was elitism, partisan politics, and anti-Irish/German sentiment, but not all of it.

Its very relevant and I think it might be of use to people, so a reminder that I wrote a book about how exaggerated fears of immigrant crime intensified repressive policing in the US and the origins of police involvement in deportations/immigration exclusion.
