TACOMA, Washington — The spread of bad information is what “fueled” a self-declared antifa supporter’s shooting rampage and arson attempt at a federal immigration detention facility here this summer, according to the U.S. Immigration and Customs Enforcement official who runs the center.

In the two months since the incident, the political climate has not cooled. Employees who work at the privately-run Northwest ICE Processing Center, maintained by the private sector GEO Group, have received threatening postcards in the mail.
