The Canadian Broadcasting Corporation (CBC) recently ran this headline (both the title and sub-title are noteworthy):

Federal government quietly compensates daughter of brainwashing experiments victim
Lawsuit filed after The Fifth Estate re-aired documentary about Dr. Ewen Cameron’s CIA-funded experiments

I’ve mentioned the film (not a documentary) called “The Sleep Room” before on this blog. It’s very good. You get a clear idea of what Cameron did, the CIA’s role, why the CIA was able to circumvent legal consequences, and the reality of MK-ULTRA. It’s story-telling that is based on historical events. The Fifth Estate documentary has the same goals. I recommend watching both.
