🚨NEW REPORT: Most people think of probation and parole as pathways away from the carceral system — but that couldn't be further from the truth. New data reveal how community supervision has grown in parallel with mass incarceration and widened the net of social control 🧵

Immigration policing & detention now make up 13% of all government spending on the criminal legal system. The U.S.’s commitment to the deportation agenda comes at a steep financial and moral cost.
Infographic with text: Since 2017, funding for immigration policing & detention has increased by 171% while funding for libraries has increased only by 22%. Not adjusted for inflation.

Mass incarceration is shaving years off people's lives. Older adults who have ever been behind bars are expected to live nearly 6 fewer years than similar peers who have never been incarcerated:

1 in 61 people nationwide are under some form of correctional control — and the vast majority of them are on probation or parole. Mass punishment in the U.S. is off the charts, even in "progressive" states.

Trump's deportation agenda isn't possible without the help of local law enforcement, and sheriffs know that. Even in states like Maryland, where formal agreements with ICE are banned, many people have been detained by ICE via informal local cooperation: nytimes.com/2026/06/12/us/sh…

Sheriffs in Maryland Challenge State Limits on Cooperation With ICE (Gift Article)

A lawsuit by a group of 17 county law enforcement officers is another front in the Trump-era fight over local police’s role in immigration enforcement.

Importantly, the people victimized by informal collaborations between ICE & local police are often ordinary residents who come in contact with the law through commonplace interactions, like a traffic stop. For example 👇 theintercept.com/2025/07/09/…

Georgia Police Arrest Farmworkers — Then Get Warrants From DHS

Georgia authorities said their goal was to serve warrants for crimes against children. They swept people up and got immigration detainers later.

Banning formal contracts with ICE is not enough. To actually keep communities safe, states must go beyond that and block all informal collaboration with federal agencies as well. Learn more 👇 prisonpolicy.org/blog/2025/1…

An increased visibility of prison journalism is vitally necessary, though it alone will not turn the tide of a sclerotic, brutal political system.

Thousands of people detained by ICE are actually held in local, publicly operated jails. These facilities–run by elected sheriffs–are making money off of the federal government's deportation agenda.
U.S. map showing that in 25 states and D.C., federal agencies like ICE and the U.S. Marshals only detain people using local jails. In other states, jails play a part in the detention network alongside federal or private facilities. In Arizona, Delaware, and Hawaii no local jails provide substantial detention space to these agencies.

As millions of formerly incarcerated people age into older adulthood, approximately 1 in 15 adults aged 50 now has a history of incarceration, facing an elevated risk of death and serious medical conditions. It's clear that mass incarceration has created a public health crisis.
