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 https://www.aclupa.org/news/2012/11/14/city-pittsburgh-settles-g-20-lawsuits https://www.aclupa.org/news/2012/11/14/city-pittsburgh-settl... though it is known to have been deployed but not used as a weapon earlier than that.
