I wonder if there might be prosecutions in 30 years. That's long enough for people to come around and for the perpetrators to still be alive. If evaluated as a strictly criminal matter, these are the sorts of crimes that do not have a statute of limitations, though the fact they were official duties might activate one.
There's no precedent for that in American history, though, and while the CIA torture program was unmistakably evil, it's far from the worst thing that has happened in the US over the last 100 years.
They have a pretty nasty history in central and south America.
The CIA have been plugging away for decades, supporting right wing paramilitaries and anyone that could help them dissuade any kind of social of left leaning politics from their 'backyard', and they didn't care who died in the process.
