That's just it. It was a very long time ago. Not many CIA employees are still there.

That's not reason to trust it. But "a bad thing happened in the 80s and that's all I need to know" isn't a compelling argument either.

I'm missing the part where there has been institutional reform since then. Otherwise, the mandate and policies that fostered those affairs are still in place, no?

The agency has been through several reforms since then, most notably the complete reorg after 9/11.

Like I said, that's not the same as knowing that they're following the rules now. But it isn't the same organization by any stretch.

Essentially goes back to the start, bunch of rich nepo kids playing spy. See Sidney Gottlieb for a fun story.
