Minnesota State Patrol uses long range acoustic device, first used by military, to disperse Maple Grove protesters

Dozens of protesters were detained Monday night after making a lot of noise outside a hotel where they believed the Border Patrol commander was staying.
Something troopers threatened to use to clear the crowd made a lot of ears perk up. It's called a "long range acoustic device," or LRAD.
Minnesota State Patrol troopers used a powerful sound system first used by the military in Maple Grove, Minnesota, to communicate and disperse noisy protesters.
"The LRAD is like a loudspeaker, but it focuses the sound in a narrow cone, so that if you're inside the cone, it's extremely loud," said retired Marine Colonel Mark Cancian, a senior adviser for the Center for Strategic and International Studies.
. . . Police say they arrested 26 people for unlawful assembly and misdemeanor riot charges.
