PORTLAND, Ore. (AP) — Portland police said they detained a crowd of about 100 protesters Friday night when violence broke out during a demonstration, halting the march minutes after it started. Thirteen people were charged with crimes.
The mass detainment shortly after 9 p.m. Friday in the Pearl District appeared to an example of kettling, a police tactic of surrounding a crowd and containing people within a perimeter, The Oregonian/OregonLive.com reported.
