Clearly now the Atty. Gen. is responsible for preventing abuses within the FBI and CIA and clearly they are failing although two years later all of the people involved in the FiISA and Trump and Hilary whitewash scandals have resigned or been fired, but none of them have yet to be charged in spite of evident crimes. And they are still doing things like raiding the homes of protected whistleblowers. And the head of CIA lied under oath to the Senate about spying on the Senate, and no criminal charges have ever been filed, in fact it took a long time for him to lose his security clearance, And losing the election for him to lose his job.
And you're claiming that having only one agency will increase accountability as opposed to having only one Atty. Gen.? I don't get it?
The Atty. Gen. clearly is responsible for prosecuting abuses like FISA/trump investigation based on steele Dossier, for example https://heartiste.wordpress.com/2018/12/05/deep-state-update-2/ , the Hillary Clinton obstruction of justice destroying her emails rather than comply with the subpoena issued, the CIA spying on Congress and Brennan the director lying about it under oath to Congress, and then admitting that he had lied under oath to Congress, and not even losing his job until his party lost the election. We have centralized accountability and it isn't working.
