PRISM was an NSA operation, so it's not clear how that is evidence against his claim that the CIA is more responsible with their cyber offense/surveillance than the NSA. If anything it seems to lend even more credence to his point.
That would assume that NSA and CIA do not share informations. So that actions from the first don't benefit the other. It would be foolish. No need to create 2 mass system if your brother has one and you can use it as much as you want.
