Although initially seen as another fanciful conspiracy theory, this one turned out to be true. The CIA really did run secret mind-control experiments on American citizens from the 1950s until 1973, using "electronics, hypnosis, sensory deprivation and verbal and sexual abuse". In 1995, President Bill Clinton issued a formal apology for Project MKUltra, as it was known. It is believed that 'Unabomber' Theodore Kaczynski was part of these experiments, although that detail has yet to be confirmed.
