J Edgar Hoover wanted to round up all the "leftists" and put them in camps.

I put quotes around leftist because simply not hating black people was enough to get you on that list.

Fun new things keep coming out.

People are so unaware how common politically motivated murder was in the late 19th/early 20th century in the US. Our country is rittled with shallow graves belonging to labor and civil rights activists. Wikipedia for example has a list documenting anti-labor murders totaling just over 1100 that we know of. Much of that violence was especially targeted towards black labor organizers.

In both the BLM movement and OWS, leaders and organizers were still meeting untimely deaths and I don't think the clandestine agencies of government have changed enough, (or at all), to rule them out.
