They have (also known as an "LRAD")

I know it was deployed in the past month Buffalo, Portland, Seattle, New York and Washington DC at least, and I'm sure many more police departments have used it.

These should be banned along with tear gas, rubber bullets and flash grenades. The indiscriminate nature and damage these weapons cause is the definition of excessive force.

EDIT: Sorry, was mistaken. ADS is not the same as LRAD - though neither should be in the hands of local police departments.




Fortunately not the same devices. The ADS gives people the sensation their skin is burning. From wikipedia:

> The ADS works by firing a high-powered (100 kW output power) beam of 95 GHz waves at a target, which corresponds to a wavelength of 3.2 mm. The ADS millimeter wave energy works on a similar principle as a microwave oven, exciting the water and fat molecules in the skin, and instantly heating them via dielectric heating.

Waterboarding gives people the sensation of drowning. This is an instrument of torture.


I think using the word "sensation" is even downplaying things. Their skin is burning. People are drowning. It just (usually) stops before permanent injury or death.


Different systems. LRAD is acoustic, ADS is radio frequency heating.
