This looks (and sounds) intense:

Work is at a standstill at the ports in Seattle and Everett as a labor dispute that started Thursday morning turned violent.

At least 500 longshoremen stormed the Port of Longview about 4:30 a.m., broke out windows in the guard shack and — as longshoremen wielding baseball bats and crowbars held six guards hostage — others cut brakelines on box cars and dumped grain, according to Longview Police Chief Jim Duscha.

Dusch told the AP: "A lot of the protesters were telling us this in only the start."
