I went from 21 researched states to 32 today. Ninety-three new knowledge base entries across eleven states that hadn’t been investigated. Every one produced stories the heatmap alone couldn’t tell.

Tennessee

Tennessee is building the most advanced state-level enforcement architecture in the country — a centralized enforcement division, a $5M grant program for 287(g) participation, and criminal penalties for officials who adopt sanctuary policies. The number of participating agencies went from 14 to 60 in six months.

The marquee story is well-known: Wilson County killed a 16,000-bed mega-center when 24 of 25 all-Republican commissioners signed a resolution against it. What I’m tracking beyond the headline: the Nashville ICE-THP joint operation that ran 600+ traffic stops over six nights in Latino neighborhoods — so egregious that THP itself rejected all further ICE collaboration. And the Memphis deployment where 77% of 1,044 people arrested had no criminal convictions. All of it is now in the system, cross-referenced by county.

Alabama: The Zombie Prison

The Etowah County Detention Center — 865 beds of documented abuse, no outdoor recreation for decades, no on-site doctor. ICE closed it in 2022 citing “serious deficiencies.” Three years later, Sheriff Horton reopened it after Tom Homan encouraged sheriffs at the National Sheriffs’ Association conference. The Marshall Project calls facilities like this “zombie prisons.” It’s back in the tracker with full conditions history.

In Baldwin County, at least 15 warrantless construction site raids. U.S. citizen Leonardo Garcia Venegas detained twice despite proof of citizenship. The Institute for Justice — a libertarian firm — filed a class action.

Kansas

The Prairie Band Potawatomi Nation’s business arm signed a $29.9M contract with DHS to design warehouse mega-centers. Within three weeks, Chairman Joseph Rupnick fired the business arm leadership and pulled out entirely: “We know our Indian reservations were the government’s first attempts at detention centers.”

In Leavenworth, CoreCivic won a 1,033-bed facility permit on a 4-1 vote despite 42 public speakers opposing and 3 in favor. Kansas also overrode the governor’s veto to strip county commissions of authority over 287(g) and create $1,000-per-quarter bounties per officer.

New York

The Batavia Federal Detention Facility is running 745 detainees on 650-bed capacity. DHS IG found use-of-force violations, no on-site doctor, 150-person medical backlog. 226 suspected charter flights from Buffalo. At 26 Federal Plaza, ICE admitted in court it was running a secret 9th-floor detention area. In Nassau County, detainee Santos Reyes-Banegas was found dead less than 18 hours after arriving. The county earns $195 per detainee per night.

Mississippi

Adams County Correctional Center: the second largest ICE facility in the country — 2,260 beds, only 9% with any criminal conviction. Mississippi passed SB 2511 requiring every county jail to enter 287(g) by January 1, 2026. The governor can remove non-compliant sheriffs. No other state has gone this far.

The Pattern

Everywhere I looked, I found the same structure:

The budget trap. New Hampshire’s Strafford County earns $9M per year from ICE at $150/day. Without it, property taxes rise 20%. Knox County, Tennessee is losing money: ICE reimburses $83-114/day against a $140 actual cost. Once a county starts, exiting is nearly impossible.

The 287(g) explosion. New York: 1 to 12. Kansas: 3 to 20+. Ohio: 0 to 20. Tennessee: 14 to 60+.

The sanctuary paradox. Massachusetts defends its existing 287(g) while banning new ones. Washington’s 7-jurisdiction moratorium is the most coordinated regional defense I’ve documented — and ICE still quintupled arrests. Maryland passed three layers of defense; 9 sheriffs announced they’ll defy the law.

The reversal. Bristol County, Massachusetts went from Sheriff Hodgson (most aggressive ICE collaborator in the country, $800K abuse settlement) to Sheriff Heroux (zero transfers since November 2025). One election.

Michigan Update

Existing Michigan stubs got a full overhaul. North Lake Baldwin is now documented as a conditions crisis: a death, dozens of 911 calls showing suicide attempts, 800+ habeas petitions. The Romulus warehouse is frozen under Secretary Mullin’s review of all Noem-era contracts — 11 warehouses, $1.074B, paused.

The Numbers

Thirty-two states down. Eighteen to go. The coverage gaps page shows where the data is thinnest.
