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.

The Minnesota State Patrol says it has had an LRAD since 2013 and uses it to make sure "...entire groups can hear when an event is declared unlawful and they have been told to disperse." During the Maple Grove protest, state patrol says officers checked the volume, issued dispersal notices, and did not use tones or sirens despite what has been reported on social media.
