In the early 1980s, victims of Dr. Ewen Cameron’s mind-altering experiments at the Allan Memorial Institute began a slow process of finding each other and building a case against the CIA for funding Cameron's work. The legacy of that case has played a key role in two separate lawsuits in progress today. These new lawsuits represent the interests of hundreds of families still seeking justice for the brutal “treatments” their loved ones were subjected to decades ago.

"Madness: The Secret Mission for Mind Control and the People Who Paid the Price" -- an investigative series in 5 parts -- unravels the shocking history of CIA-funded mind-control experiments. This is Part 4. If you haven't heard Parts 1 through 3 yet, you can find them here, here and here.
