A troubling proposal involving military technology
The Trump administration has considered using a directed-energy system known as the Active Denial System in connection with the U.S. border. Government authorization for testing or evaluation does not establish that the device has been deployed routinely against people crossing the border. That distinction is central to assessing the report.
How the technology produces pain
The Active Denial System uses a focused beam of millimeter-wave electromagnetic energy, commonly described around 95 gigahertz, to heat the surface of the skin rapidly. The intended response is an immediate sensation that prompts a person to move away. It is not a science-fiction laser that vaporizes targets, nor is it harmless simply because it is marketed as ‘nonlethal.’
Why the safety debate persists
The effects depend on exposure conditions, distance, the system’s controls, and whether a person is able to escape the beam. Risk assessment should consider burns, eye exposure, incapacitated individuals, crowd conditions, and vulnerable people. Testing protocols under controlled conditions do not automatically establish safety in unpredictable real-world encounters.
A border is not a battlefield
Military equipment developed for area denial raises different legal and ethical questions when proposed for use around civilians, asylum seekers, children, and other people at a border. Even a device intended to avoid fatalities can constitute force that requires legal authority, necessity, proportionality, oversight, and meaningful avenues for accountability.
What officials have and have not established
The publicly described administration consideration and testing do not amount to proof of a completed operational deployment. Reporting should distinguish internal proposals, authorized trials, procurement decisions, rules of engagement, and documented use. Each step requires separate evidence.
Questions an independent inquiry should answer
Who authorized the evaluation? What operational problem was the system intended to solve? What human-subject or safety testing supports it? What policies govern its use, incident reporting, and medical assistance? Could the same objectives be met with less harmful methods? Are Congress and the public receiving enough information to evaluate the decision?
Apep Bar asks
When a government calls a pain-inducing weapon ‘nonlethal,’ should that label reassure the public—or trigger closer questions about when, where, and against whom it may be used?
