I was inducted at some point around the age of 4 in the late 1960's. Sometime between ages 4 and 5 I was given LSD in a hospital setting. I have vivid memories of the hallucinatory effect, how the nurse's cap turned into a rainbow colored snake and then a feather boa. Not all of us are so damaged that we cannot function or contribute positively to society, and we do, despite the ostracism, and cold denial with which our stories are commonly met. It continues to be a long wait for researchers to catch up and begin exposing these horrendous crimes. We need good researchers too, because there is often more discrediting disinformation than good available, especially on the Internet.
I am aware of at least 2 FOIA documents mentioning work on children, including one that describes how two girls were hypno-programmed to arm a bomb. As another commenter mentioned, we also have survivor testimony before Congress (1995 radiation hearings), and at least one survey conducted by clinicians with more than 500 respondents reporting experiences of MK-Ultra style intentional manipulation.
For those interested in the Olson episode, I suggest H.P. Albarelli's exhaustive study, "A Terrible Mistake: The Murder of Frank Olson and The CIA's Cold War Experiments", published in 2009. He makes a convincing case for how Mr. Olson met his end on the sidewalk, as the CIA's first known murder of one of its own.
I also prefer Walter Bowart's "Operation Mind Control" over Marks' work. It's based on the same documentation, but Bowart provides a much more accurate description of the techniques developed during the 50's and 60's, and his conclusion, that this "work" continues is also correct. I can't point to a source for this, I don't believe it is in any published survivor account, but we do have young people coming forward as survivors today, people who were born in the 1980's, and 1990's. Together with the reports of other survivors, and my own experience, I can say mind control is still operational.
