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.
