Who exactly was punished by that EO? You are proving my point, even the most "push back" IAs have seen in terms of concrete actions against them led to... a directive that forbid them from murdering people in foreign countries. No actual consequences for anyone involved, no one got even a slap on the wrist in terms of actual consequences. And that's after the church committee, which revealed some super damning stuff.
Oh, and they went back to doing it after a few decades.
Are you really asking me to cite classified operations?
And the fact that subsequent Executive Orders explicitly loosened the reigns on intelligence collection (and assassination with respect to "terrorists") indicates that yes, the original orders did restrict intelligence operations.
It sounds like you are claiming that IA’s have been punished for their abuses, but we’ll just have to trust you on it because the punishments were classified operations. Doesn’t make sense at all, unless you’re saying that the punishments were certain spy chiefs secretly murdered or something.
You make a good point. While people may have an issue with FISA being opaque they do not consider that maybe it being opaque is good for reasons that cannot be explained. With an explanation like that, how could anyone have a problem with such a thing?
