Federal Bureau of Investigation Assessment titled:  White Supremacist Infiltration of Law Enforcement

Since coming to law enforcement attention in late 2004, the term "ghost skins" has gained currency among white supremacists to describe those who avoid overt displays of their beliefs to blend into society and covertly advance white supremacist causes.

Might help to explain what we are seeing.  I found the white power texts of the SF cops to be especially concerning considering I am from that area and would have thought they wouldn't want to work in the city.  But maybe they do.  Maybe that's exactly what they want.  Even more reason for cops to start to actual police themselves.  Though, that didn't work out for Serpico.

I also read a blog that stated one of the cops killed in Dallas was a neo nazi, which lead me down the wormhole to this.   The blog contained no proof, so I won't link to it.  It's completely unsubstantiated garbage until some actual proof is presented.

Interesting to think about.
