I've been involved with a local militia for several years, and they absolutely do have strong connections with law enforcement (and, to a lesser extent, military) - some cops are members outright, others are not formally affiliated but provide support, training etc.

The cops I've seen in those meetings talking about how the communities they are policing are "subhuman animals" that "just need a bullet" are still in Seattle PD, as well.

They also had connections with some state legislature members, such as Matt Shea.

Ok, but so what though? Are they actively committing crimes or doing something crazy with regard to the militia? I mean we have tons of evidence of cops doing crazy shit in uniform and on the record and nothing happens.

The report identified (but didn't directly name) 1 sheriff. Assuming it’s the current sheriff, a quick google of his background + the fact that he "facilitated" the militia members FBI interview gives a pretty strong hint why mainstream media would not pick up this story.
