Can you envision circumstances in which you would not know the details?
If the CIA had projects whereby they were trying to blow the circuits of individuals (and they did have those kinds of projects) could you envision such a person killing someone??? And then it never coming to light that the person was experimented on?
A US Marshall was slipped LSD. By accident or on purpose. It probably was on purpose but he might not have been the target.
He went rogue. He describes what he went through.
I can see someone going on a killing spree.
None of this means that it happened in this case.
But you can’t tell me that it isn’t possible given the lengths our government has gone to in the past while experimenting.
I believe Colby was killed because of The Franklin Cover Up.
But then , maybe someone else knocked him off for another reason. Some say Clintons did it.
Idle speculation about super-secret government mind-bending experiments that program random civilians to mass murder may be fun but they fall into the "paul is dead" category of diversion.
