Army study: ICE’s shock gloves cause pain, compliance, fear

The shock gloves immigration agents could soon use to control detainees and protesters worked so powerfully during a military exercise that participants felt intense pain, stopped fighting immediately and feared additional exposures, according to a previously unreleased Army study.

Immigration and Customs Enforcement leaders were aware of the findings before signing a $16.7 million contract to purchase 6,000 pairs of shock gloves in August, according to records obtained by the watchdog group American Oversight and shared with The Associated Press.

The shocks had a profound impact on Army employees who played the role of combative prisoners during the exercise, which took place at the military prison at Fort Leavenworth in Kansas in October 2024. The participants, several of whom were large-statured men, stopped resisting seconds after officers applied shocks by touching gloves to their skin, and were left with “fatigue, soreness and excessive apprehensiveness to being shocked again,” the study found.

“After experiencing the effects of the GLOVE, ... participants stated just seeing the GLOVE was enough to make them want to comply,” the authors wrote.

Watchdog says gloves cause pain and raise safety concerns

ICE has called the gloves “distraction and de-escalation devices" that will be safer than other non-lethal options to subdue targets for arrest and deportation and protesters who create civil disturbances. The agency has argued the rapid compliance they cause will keep officers safer and prevent incidents from requiring potentially lethal force.

But critics have warned the gloves will give ICE another weapon to intimidate and brutalize people even as the agency is under fire for excessive force that has left a trail of deaths and injuries across the nation. The gloves, they note, are easy to discharge, do not leave a mark and have not been extensively used in settings outside of jails. The manufacturer warns they should not be used on high-risk populations such as kids, pregnant women or disabled people.

“The military assessment in ICE’s own files shows that these gloves can cause ‘intense pain’ and force compliance. It does not establish that they are safe,” said Chioma Chukwu, executive director of American Oversight. “Everyone should be alarmed that ICE is preparing to deploy a tool designed to inflict, at best, intense pain, without showing that it is safe for the people who will be subjected to it.”

ICE released the study and other documents to American Oversight as part of the group's Freedom of Information Act lawsuit against the agency seeking records related to its use of force.

Army study found shock gloves triggered ‘immediate’ compliance

The military prison study assessed whether the gloves could be used effectively to forcibly remove combative prisoners from their cells, to respond to disturbances in common areas and to transport uncooperative inmates. Role-playing employees conducted several scenarios with and without the gloves to test their impact, including violent encounters in which inmates were to fight as hard as they could.

The study found the devices “increased the efficiency” of teams carrying out forced cell extractions and responding to disturbances by reducing the length of physical encounters, keeping guards from becoming exhausted and preventing injuries. They did not “significantly change” the time it took to control inmates during escorts but required less effort.

“GLOVE provides a boost in confidence to smaller or less trained members,” the study found. “Inmate compliance was immediate” compared to other methods, it added.

The electric jolt does not cause the body to freeze like a Taser shock does, but instead “works by overloading the peripheral nerve endings” of the skin to cause pain, the study said. Participants who were wet or had oil on their skin described even more powerful shocks, with one reporting discomfort for 30 minutes afterward.

Senator says ICE hasn't responded to demand for details on glove use

ICE's contract requires the manufacturer, Compliant Technologies LLC, to deliver the gloves within six months. Its owner, Jeff Niklaus, said he was unavailable for an interview, citing a busy workload.

White House border czar Tom Homan has said it could “be awhile” before the gloves are in the field because ICE is still ironing out training and policy issues. ICE did not respond to an AP request for comment on the study and the status of the rollout.

U.S. Sen. Catherine Cortez Masto of Nevada said ICE has not responded to an Aug. 27 letter in which she and 15 other Democratic Senate colleagues called for ICE to abandon its plan to buy the gloves or explain how they would be used and managed to avoid abuse. She said she still wants answers.

“Without ICE’s responses to legitimate questions from 16 United States Senators, the American public is being left in the dark about how these electric shock gloves are being deployed and what, if any, training the agents who use them have received,” she said.
