An “active-shooter” training exercise at the William Kenzo Nakamura U.S. Courthouse in downtown Seattle tied up traffic Thursday during the morning commute.

The training involved the Federal Protective Service, the U.S. Marshals Service, the FBI, Seattle police and the King County Sheriff’s Office, said Melissa Muir, director of administrative services for U.S. District Court. She said officers were training for an “active shooter, active threat situation.”

Muir said Circuit Court Judge Richard Tallman has long pushed for the joint “hands-on practice” at the federal courthouse at 1010 Fifth Ave.

“If you’re not actively planning for it you’re not ready,” Muir said.

During the training, traffic on Sixth Avenue was diverted while a Federal Protective Service mobile-command vehicle blocked the street, she said. The training session lasted from about 9 to 10 a.m.

Additional training sessions will be held at the U.S. District Courthouse, 700 Stewart St.
