OPB joint investigation: FBI warns of neo-Nazi plots as attacks on Northwest power grid spike

Attacks on electrical substations are on the rise in the Northwest. There have been 15 since June, more than in the previous six years combined.

According to a joint investigation by Oregon Public Broadcasting and KUOW, in most cases, the motives aren't known. But as the FBI and extremism researchers have noted, neo-Nazis have been calling for just such attacks.

"The individuals of concern believe that an attack on electrical infrastructure will contribute to their ideological goal of causing societal collapse and a subsequent race war in the United States," according to an FBI memo.
