@prisonpolicy.orgReposted by @jkangbrown.bsky.socialInstead of releasing people, jails are increasingly complying with ICE detainers and handing folks over to the federal agency. ➡️ Since 2024, the average number of daily detainer-related arrests has grown by 144%
technically speaking, your local cops ARE part of ICE. in fact, a lot of them volunteer labor for ICE.
@jkangbrown.bsky.socialThe full data table along with links to the new monthly reports we received via FOIA request here: www.prisonpolicy.org/data/usms_de...
@jkangbrown.bsky.socialUpdated the graphic to show the increased detention in summer 2026.
After @jkangbrown.bsky.social and I published analysis of ICE arrest data, Jacob got updated USMS figures.
We can now see the feds have expanded the number of people detained on federal immigration charges by *29%* since 2024, circumventing sanctuary laws www.prisonpolicy.org/blog/2026/10...
@prisonpolicy.orgReposted by @jkangbrown.bsky.social🚨Most state sanctuary policies restrict collaboration with ICE & ignore the U.S. Marshals. The Trump admin has used this loophole to fuel its deportation agenda: ➡️ New data show that since 2024, the number of people detained for federal criminal immigration charges is up 25%
@tituslegaldesign.comReposted by @jkangbrown.bsky.socialNew report from @jkangbrown.bsky.social + @bson.bsky.social at @prisonpolicy.org does a great job of capturing this ⤵️ through analysis of ICE detainer and arrest data.
Worth reading to understand the broad set of tools available to ICE via local and state law enforcement collaboration.
@prisonpolicy.orgReposted by @jkangbrown.bsky.social🚨NEW: The Trump admin has demanded local & state collusion on immigration enforcement, promising to pull back on community arrests in return. But new data reveal that it never delivered on that promise, and ICE's assault on communities only worsened 🧵
@jkangbrown.bsky.socialAnd thank you to all my wonderful colleagues at @prisonpolicy.org who make this work possible, the people at the Deportation Data Project that were able to secure the ICE detainer and arrest data that we analyzed, and others that helped or answered questions.

@jkangbrown.bsky.socialMany states could to make stronger policy like Oregon to block ICE detainers and close the federal criminalization loophole that allows ICE to use a federal criminal charge put people in local jails with US Marshals contracts.
@jkangbrown.bsky.socialFinally, US Attorneys are filing more cases and more people are being detained facing immgiration-related criminal charges, the new FOIA docs that we received show the number of people in US Marshals detention facing those charges are up 25% since FY2024.
@jkangbrown.bsky.socialStates with the strongest protections have fewer ICE arrests, and those with wishy-washy policy like New Jersey have arrest rates similar to collaborator states like Florida or Georgia.
@jkangbrown.bsky.socialThe ICE detainer system appears to be fragile -- primarily operating out of a couple of ICE-leased office buildings, and requiring routine actions from local law enforcement to work.
@jkangbrown.bsky.socialWhile the scope of law enforcement collaboration on ICE arrests has expanded via 287(g) and other methods detainers still play a central role.
@jkangbrown.bsky.socialThe briefing digs into the increased use of detainer-related arrests during the Trump administration, and what states can do about it.
@jkangbrown.bsky.socialNew analysis of ICE detainers and arrests in 2026 with @bson.bsky.social for @prisonpolicy.org shows that law enforcement collusion tends to expand ICE arrests, and that the mass deportation project falters in places that resist.
