Right, so, male influencers are being sent out to tell Black people that resisting data centers is wrong actually because people don't understand how to really measure their water use. It’s an appeal to scientific expertise intended to intimidate Black people.

It's an estimate based on previous years' fringe formulae from the Dept. of Finance, so, grains of salt all 'round, but I think this is closer to the real cost of service for each department's workforce than anything else floating around out there. And the effects are pretty striking:

One of the most cited studies supporting ShotSpotter was an op-ed vetted by the Tribune whose results were not statistically significant and published by a lab hired to initially operate ShotSpotter. Expect more of this tech-washing in the years to come. www.chicagotribune.com/2026/10/17/e...

chicagotribune.comEditorial: Vote ‘yes’ on bringing back a gunshot detection service in ChicagoSince the mayor canceled the ShotSpotter contract we’ve seen dozens of cases of gunshot victims lying wounded or dead for hours.

Inspired to see Mexican-American Artist Vincent Valdez on this list of MacArthur Fellows this year. An incredible incredible artist. I've been following his work for years. So well-deserved!

yet another case of this admin using concepts against themselves—here appropriating fundamental cause theory and social determinants of health to talk about ED as a “root cause of infertility”, rather than preventing infant mortality.

A growing epidemic of alleged police abuse of Flock's vast surveillance system has led Homer Glen to (for now) halt plate reader use within its borders. West Chicago, Channahon and the Will County sheriff all have officers on leave for alleged unauthorized searches of license plate-tracking data.

Part-time Prairie Grove officer William Copp allegedly used Flock's license-plate readers to stalk exes and others through 246 searches of their movements, prosecutors say. When he was arrested this summer, the Chicago area had already emerged as ground zero in a nationwide fight over Flock. 🧵/12

There is growing national momentum against ALPR mass surveillance. In the past year, dozens of cities have ended their contracts with Flock and other vendors. In the past week, Florida has ordered the removal of ALPRs from some roads, and Texas has ended its funding of city ALPRs. (1/2)

I can't help but observe that news outlet concerns over "causal claims" in studies about surveillance technology effects (like in our "After ShotSpotter" study) suddenly disappear when Flock's marketing team says license plate readers = less crime/more arrests. www.wbez.org/public-safet...

"The left does not need to pursue its own exoneration in this moment. There is no reason to indulge the fantasy that we governed the nation during these recent, disastrous years, or that our country's brief flirtation with racial justice was an unthinkable disaster with countless innocent victims."

organizingmythoughts.orgWoke What? Let's Be Fucking SeriousOur politics are not the politics that have detached this country from reality, or normalized increasingly inhuman policies.

I’d add the consolidation/efficiency argument never gets applied to police or tech. Shotspotter advocates say “But if it saves one life, it’s worth the it!” Imagine if that logic were applied to health care infrastructure, teachers, CVI, or any life saving aspect of the safety net.

The coupling of contradictory pledges for efficiency + more policing has happened enough times that it’s hard to not simply call this racialized neoliberalism. And its power seems to come from how many people take this as the norm.

Denali@denali.bsky.social

And on public safety, no one who is running for Mayor and talking about the city's fiscal house or using not one more dollar rhetoric should have to talk CPD budget. If they treat fiscal health and cost of policing as two separate issues it's ok to not listen to them about the city's finances.

Chicago Mayoral candidates’ position on shotspotter is a good litmus test for who is going to let AI “move fast and break things” at the expense of communities and taxpayers.

A great new study on the effect of CPD’s sentiment dashboard, which increases trust in police among white respondents and decreases trust among Black respondents. This complicates the idea of investing in data dashboards. www.science.org/doi/abs/10.1...

A reason why the study of culture and propaganda is just as important as behavioral science for studying public safety.

WTTW - Chicago PBS@wttw.bsky.social

More Chicagoans believe violent crime has increased in the city, according to a new public opinion poll, even as shootings and homicides throughout 2026 are essentially the same as last year, which ended with the fewest recorded killings in 60 years. https://to.wttw.com/4yw0McF

For centuries, courts and lawmakers have been the primary regulators of law enforcement investigations, placing legal limits on how police can collect information. Now, companies like Google are becoming just as influential, writes Texas A&M University School of Law professor Hannah Bloch-Wehba.

UPDATE - We got some good questions about seasonality, and added a map to the study website comparing response times in the first 9 months of 2025 to first 9 months of 2024. The change in response times is more modest (2 minute improvement on average), but the overall trend still holds.

Second, using 911 calls in response to shots fired would have rendered us (rightfully) vulnerable to the critique of inflating our results. 911 calls about shots fired are a flawed measure. Not everyone calls. When they do, it's probably serious. Priority 1 calls was the fairer measure.

Some asked the great question of why we didn't include response times to shots fired. Two reasons: 1) the city turned off all microphones in September 2024, hence there were no SS alerts to study. Had the city staggered the decommissioning, we could have instrumented that, but it didn't.

Important to note that these declines happened without a snap curfew and without restoring shotspotter. This will be crucial to remember when some elected officials try to seize on the next moral panic to pour more taxpayer money to fund bad crime-fighting ideas.

In a year when Donald Trump called Chicago the “most dangerous city in the world," citywide killings fell to a 60-year low, down ~30% from 2024, as overall crime kept dropping. It’s the first time in a decade the city has had <500 slayings in a year. 🧵/6 w/ @sophiesherry.bsky.social & Kade Heather

Trump declares war on state AI laws, including a law I passed to ensure transparency of AI safety protocols. He’s doing so purportedly to promote U.S. AI “dominance.” Of course, he just authorized chip sales to China & Saudi Arabia: the exact opposite of ensuring U.S. dominance.

This is one story on lisence plate readers. A quick search about other surveillance (especially police access to databases) will reveal this is a major problem for stalking and gendered violence. With all the new data streams going into lookup tools these days, this problem will only get worse.

Matthew Guariglia@mguariglia.bsky.social

Police have access to massive surveillance networks that track the public whether they are suspects or not. That means probably for every 1 officer caught using the system to harass or spy on people they have feuds with, ex's, activists, journalists, there are probably 100 more we don't know about.
