The system in question is basically just a directed microwave emitter. It is designed to heat up the first ~0.5mm of your skin.

It's safety is basically completely a function of the operator. Since the beam will keep depositing energy (ie heating), if the beam is held on a target, it will incur more and more heating (and potentially harm).

In proper usage, safety is ensured through the combination of operator training, selection of proper settings, and induced compliance. If you have a shitty operator, risk of over exposure increases. The nature of this device means that it's not a barrier, it's a beam.

During earlier testing, they were able to induce second degree burns on a test subject due to incorrect power and duration settings.

There's no way I'd trust this in the hands of anyone, especially those operating in the service of the current administration. They say they want to use it to "protect the border" but there are reports that they'd used it domestically already.

Considering the non-tolerance of public protest and the "promise" of non-lethality, I could imagine this becoming a regular tool in population control if things don't change.

...and one need only watch videos of "trained officers" hosing people with pepper spray to envision how that will turn out.

Also try not to think about contact lenses, piercings, jewelry, pacemakers, etc.

for certain types of tools (and I'd certainly class weapons as this type) you have to assume that a certain number of operators will be, as you put it, "shitty". Whether it's because they're having a bad day, are genuinely incompetent, are malicious, whatever the reason---some percentage of the operators will be using your tool in a way you'd discourage for PR reasons.

Maybe I am too cynical, but I don't think the people making these tools actually care about this either, not beyond the potential for bad publicity.

knowing the kind of people who sign up for ICE/CBP enforcement, I have no hope that a trained or decent operator will be behind this machine.

I expect a lot of severely traumatized people from this device

This is a weapon that will be deployed primarily against their own citizens.

The “border” extends 100 miles in-land from the actual border and encompasses 2/3 of the US population. DHS needs to be dismantled stat.

what the actual fuck.

edit: okay, first reaction, obviously not contributing to any conversation. This is barbaric and if I paid US taxes I'd be writing my government.

Kids that put hamsters, kittens or gerbils in the microwave grew up to be Republicans in charge of the military and economy.
