New York's Gun Involved Violence Elimination (GIVE) initiative reported its December data showing 20 shooting victims in all of December across 20 agencies (not NYPD) That's by far the fewest number of shooting victims recorded in a month since collection started in 2006.

New this week: I wrote about the dozen cities I found that had fewer murders in 2025 than in any of the last 50 years. A wide range of cities with incredible results.

311 is a mess, yet it's being used as if it's not!

Peak day: January 05, 2025 with 4,978 calls. Hasn't let up that much. Maybe we can't use this data to understand disorder in the city?

One address accounted for over 26% of the NYPD's 311 calls in Jan 2025. They get 1.5+ million calls per year. Seems like a problem (not with the building).

The โ€œzone strategyโ€ was Maddreyโ€™s brainchild ( drawing explicitly on Operation Impactโ€”an approach that shaped much of the departmentโ€™s leadership during their formative years as young captains.)

One of the more reckless policy decisions of the past 4 years.

Has Youth Crime in New York Risen After Raise the Age? Overall, no. In one specific area, thereโ€™s serious cause for concern.

Sometimes you can't be "data-driven."

Government plugging along in Excel! Have to be charitable.

But yes, it is ugly. It happens (NYPD, 2024):

Vital City | On Overdose Prevention Centers, Listen to Community Complaints Policymakers would be wise to listen carefully to neighborhood residents who criticize the facilities.

Good article in @vitalcitynyc.bsky.social by @katy-pugliese.bsky.social on local impacts of overdose prevention centers in NYC. She cites my work w/ @jjhall.bsky.social that found substantial property crime increases around one of the sites. Link in 2/2

Those who have taken to calling the criminal justice system the "criminal legal system" should read Greg Berman's new piece in Vital City. www.vitalcitynyc.org/articles/the...

Overdose prevention centers are saving lives (as documented in our drug issue vitalcitynyc.org/issues/issue-6). But are we listening closely enough to community concerns about them? In a new Vital City piece, @katy-pugliese.bsky.social puts her ear to the ground. www.vitalcitynyc.org/articles/on-...

This isnโ€™t that complicated: Just because New York City is safer than it was decades ago doesnโ€™t mean it is the safest itโ€™s ever been. In fact, itโ€™s gotten significantly less safe lately in some key respects. www.vitalcitynyc.org/articles/the...
