US security forces...oh good christ! And yes I do...some asshole on utube tried to show or say the US military was arresting people as well. They showed a couple of Pittsburg swat throwing some asshole in a cruiser. They were wearing woodlands. we don't wear woodlands anymore. These sound cannons are very good non-lethal weapons...better then water cannons, gas or rubber bullets...better then being beaten with a club or shield as well.
