It's not a conspiracy theory, you just aren't reading the news. The Senate Intelligence Committee has stated that they weren't aware of the CIA's bulk data collection program until the public was. Did Congress authorize CIA intervention in Iran, Guatemala, or Nicaragua? Did Congress provide effective oversight of CIA torture in the Middle East? No, because they weren't even aware of it until 2009. Are you going to claim that all these instances are one-offs, or see them as signs of a systemic problem within our intelligence agencies?
