Domestic spying is supposed to be outside the purview of the CIA.
And for that reason this report seems a little questionable.
The CIA is allowed to track communications/deliveries of contraband from foreign countries, as well as people. Then it is handed over to the FBI but if the subject has contact with people/govts overseas, the CIA can monitor it.
The CIA is not supposed to conduct domestic intelligence gathering per se. However, from personal experience as an undercover operative, I once met a foreign national who had come to the US to participate in anti-US foreign policy strategy sessions, conferences, and protests.
That person clearly would come under CIA overseas surveillance, and entry and exit surveillance, with the FBI picking up their movements/activities in the US. She was a KGB asset if not an actual KGB operative (there is a difference re “control” and “instructions”).
Other members of a Communist Party of Japan front with direct ties to KGB “peace fronts” also came to DC, about 2 miles or less from the White House. I was part of the greeting party (Communist Party USA members being the leaders of the “peace” organization here).
The world of counter-intelligence is very complex and our rules, until the Patriot Act, were basically crappy, emasculated, outdated, and not wide enough in targeting new threats to our security (who used new methods to subvert and/or attack us which were not covered in the previous laws).
Can the Patriot Act be refined and reformed where necessary? Yes. But the key question is about who is going to do the “reforming” and how much do they know of the actual world of subversion.
Also, when you have a hardcore Communist heading the House Judiciary Committee as Rep. John Conyers (D-Mich) did for a long time, how can you trust him with Top Secret intelligence?
YOU CAN’T, nor some of his staff who also had ties to Communist fronts but here and overseas. (Ex. The World Youth Festival, a Soviet operation since it was created).
The question I always ask someone about intelligence is do they know who the enemy is and where they are. If the answer (and details) are “yes”, then I have confidence in them. If not, as in some of our FBI and CIA directors, we are in deep trouble, and presently are today.
