I mean there’s an official FBI report that says it white nationalists have infiltrated police departments and another that says they use their influence to prevent convictions of domestic violence perpetrated by white nationalists. Additionally there are plenty of reports in multiple cities to show that cops often plant evidence to convict people of crimes they didn’t commit in order to aid their career. And the victims are almost always black, usually mentally disabled, and often homeless or home-insecure. So it’s not a stretch.
And I’m not talking about a conspiracy outside of the already proven idea that white nationalists have infiltrated police departments and alter evidence. One cop altering evidence for his buddies isn’t a conspiracy.
And the only thing that could be considered a “theory”/hypothesis is that this was a targeted killing, rather than a random one like the media are already painting it as. And that the police will push that scenario and refuse to investigate white nationalist groups to see which ones sent him threats. We’ll just have to wait and see on that. I suppose it depends on if any witnesses or others go to the media with evidence.
