They have been used against US citizens in the United States? That is news to me.

If they have been used in other countries against US diplomatic corps that is an act of war.

Now if a US citizen uses a visit to a foreign country to protest against a government they’re on their own. I’m sorry, but US citizens shouldn’t be engaging in that and the US state department has no obligation to protect that condition.

it's actually quite common. i have personally experienced use of LRAD by police as a weapon.

the first actual use of LRAD by police as a weapon in the united states was possibly in 2009

though it is known to have been deployed but not used as a weapon earlier than that.

but to clarify, i don't think the video posted by OP shows use of an LRAD. that is something else

The US has also in some places explicitly legalized the use of cars as a lethal weapon against protestors: https://www.nytimes.com/2021/04/21/us/politics/republican-an...

Used in 2014 against protesters in Ferguson.
