St. Louis County police used LRAD during protests surrounding the police shooting of Michael Brown in Ferguson, Missouri. Reporter Mike Tobin commented while broadcasting from Ferguson, MO on 18 August, "It doesn't have the effect of crippling people. It's just loud, it's annoying, it lets you know something big and official is coming and that's what's happening now. They can also use it as a loudspeaker to tell people to get out of the way."
