Ted Wheeler ought to talk to Jim Brunberg at Revolution Hall about Ear Damage Tort

Early this morning, Portland police officers used a sonic weapon to drive away protesters.

Speaking to reporters early Friday afternoon, Portland Police Bureau Assistant Chief Chris Davis said sometime after 1:30 Friday morning, officers in the sound truck that broadcasts communication to protesters came under attack.

Davis said the officers in the truck then deployed a tool called a "long range acoustic device," or LRAD, which Davis said "will emit a tone that is very hard to be around."

News reports say the device can generate a sound of more than 150 decibels that can be targeted and projected across long distances.

LRADs were originally developed as a tool to deter pirates but has been adopted by military and some police forces as a crowd-control device.

PPB has used an LRAD before, Davis said today, but he did not specify when. "It's very rare,"

Use of the device comes at a time when PPB is under heavy criticism for its use of CS gas, a form of tear gas, against an uprising that protests the police killing of black people. City Commissioners Chloe Eudaly and Jo Ann Hardesty have both called for a ban on tear gas
