The CIA is just a collection of people. People that make mistakes. People that have emotions and whims. People that have families and children. People that want to go home at night, take sick days, and go on vacation. There is a natural limit to what the CIA can do simply because they need humans to do it.

I don't think there's much more to the CIA than what's in these leaks. To do anything more, you'd need tens of thousands of people and huge server farms. You can't hide that stuff.
