ICE detention-center attacker killed by police was an avowed anarchist, authorities say

A man fatally shot by police Saturday after allegedly throwing “incendiary objects” at an immigration detention center in Washington state was an anarchist who claimed association with antifascists — known as antifa — according to new details released by police.

Detectives are reviewing a manifesto written and distributed by 69-year-old Willem Van Spronsen, who police said once belonged to the Puget Sound John Brown Gun Club, a self-proclaimed “anti-fascist, anti-racist, pro-worker organization.” Officers were not aware of the manifesto before the attack on the Northwest Detention Center in Tacoma, police said in a statement Thursday.
