MK Ultra on its own could count for several.

Was the experiment where they released some "harmless pathogen" (assuming your immune system is all good!) in major cities to see how they spread, resulting in some deaths/complications part of MK Ultra? Can't remember if it was under that project or part of a different one leading up to it.

The Iran/contras were CIA.

Oh also the Iranian revolution, or at least the instability that led to it.

Saddam Hussein and Osama bin Laden both started as CIA assets that got tired of being used.

A lot of attempts on Fidel Castro's life.

That's off the top of my head. There's also a bunch of fuckery in central and south America, though if I had to guess, I would guess that there has been fuckery in every single country on this planet, including countries some would have called allies. Iirc they targeted some Canadian cities for that "release the pathogen" experiment, too.

Were the Tuskegee experiments them?

I like their chatbot experiments personally

The family jewels documents are nice. After the cia had former employees "slightly" involved in Watergate, the CIA sent out a memo asking everyone for their records on things that happened that probably would be illegal.

It's like a short story collection of weird criminal shit. "We kidnapped this Russian for three years. Why? Well, he said he wanted to leave the Soviet Union after spying for us for a while and we thought that was suspicious, so we locked him in a room for a few years.". "We gave a bunch of poison to the Mafia and had them wander around Havana" "we weren't technically allowed to do that with the telephone"

Pre-cia there was the radioactive foxes.

Finally is the weirdly open CIA investment company inqtel.
