I'm willing to acknowledge that you may have access to information that proves your point.
But I know for a fact that the CIA does have a committee of elected officials that oversee it. Whether that is effective oversight is debatable, but the fact is that it exists, and they must legally disclose their actions. This means there are legal means by which they can be held to account in the cases where they do not.

And they let their own inflated egos delude themselves in believing that the overall threat posed by the Russians/Chinese (which in comparison to the US, are much weaker) is greater than that of a government that surveys/records/interferes with the lives of its own citizens.
There is no paper trail for this abuse. This is a system that should not exist.
