Except that it doesn't; NSA has a conflict of interest, but they're already split internally. Even if you split them into separate agencies they're still going to both be part of the USG so while that might reduce the risk of a conflict of interest somewhat, it wouldn't eliminate it. After all, think of the existing reaction we get when actually independent agencies of the USG throw out comments in support of NSA's signals intelligence. If the NSC, Congress's intelligence subcommittees, Executive Office of the President, Department of Justice, various Inspectors-General, Dept. of Defense, FBI, and, oh yeah, the courts can all be looped into what hacktivists claim is a vast conspiracy to violate the Constitution, then what defense would splitting IAD out really be?
