This is just classic. First they try out MKUltra in the US at taxpayers expense When it shows promise they close it down and destroy all the records. Sadly for them, some were misfiled and they turned up later on hence the Congressional investigation.

At the same time they start a continuation project in the private sector, move it to another country (Canada in this case), send funds to Canada via a circuitous route.

Now they can officially deny that anything is MKUltra related. Works every time! Even for viruses.
