A group of men detained at the T Don Hutto detention facility in Taylor, Texas — nicknamed "la perrera" (the dog pound) — mailed nearly 200 pages of handwritten testimony, drawings, and documents to the outside world. The package, routed through a detainee's relative to the Center for Popular Democracy and then to the Guardian, represents an unusually direct channel of communication from inside a system engineered to be opaque. One man, Julian Osorio Garcia, a Colombian asylum seeker, even sang protest songs over the prison pay phone. The facility, operated by private prison company CoreCivic under contract with ICE, held 497 men as of late September — near full capacity. Most were booked in 2025 or 2026; two have been held since September 2023. The majority lack criminal histories. The testimonies describe a regime where detainees feel treated as "inventory," not people — a word choice that maps neatly to the business model of a company paid per head per day. The accounts allege beatings by guards, substandard food and medical care, and the use of solitary confinement. One written account describes a Cuban man beaten to the floor and left bleeding after a confrontation over taking bread from the cafeteria. CoreCivic said the incident "was reviewed in coordination with ICE, and it was determined that excessive use of force was not used." DHS called all allegations of subprime conditions "FALSE" while declining to address specific abuse claims, saying it would not "entertain unnamed allegations from the Guardian." Osorio Garcia's case illustrates the system's catch-22 architecture. He entered the US legally in 2023 on a tourist visa, later applied for asylum after receiving threats from criminal groups in Colombia, and was granted a work permit while his case was pending. A Colombian magistrate found him to be an "indirect victim" of the country's civil conflict. He was arrested in May 2025 after a traffic stop involving local law enforcement cooperating with ICE — a growing practice. DHS says he "chose to violate our nation's laws by refusing to depart by the required date." His asylum case remains undecided. A federal judge denied his habeas petition in October. The detainees' compiled demands include faster processing of immigration cases, family reunification, release of detained children and those with developmental disabilities, and investigations into rising deaths in ICE custody. These are not radical asks — they are procedural. The men are requesting that the existing system work as designed, which is itself an indictment of how far it has drifted. The structural picture here is a private company (CoreCivic) profiting from volume and duration of detention, a federal agency (ICE) with no incentive to process cases quickly, and a population with minimal legal recourse or public visibility. The men's decision to compile testimony and mail it out — using the prison's own mail system — is an act of improvised transparency in a system built to prevent exactly that. The hand-drawn sketches of cells, hallways, and courtrooms function as both evidence and art, the visual equivalent of the protest songs sung over a crackly pay phone. DHS's blanket denial — "FALSE" in all caps — and its refusal to engage with specific allegations is the institutional equivalent of a locked door. The detainees' 200 pages of testimony are an attempt to open it. Whether anyone on the other side is listening is a separate question.
