There needs to be restrictions on both, conceptually. Actual implementation is yet to be proposed. Relying purely on data usage reform is a pipe dream, just as the ideal of having an intelligence agency that works completely within the framework of law. It didn't work for the Church Committee, and the whole point of an intelligence agency is that it will do borderline or outright illegal acts (black bag operations, disinformation, psyops, etc.) to further state interests. Almost inevitably, this includes domestic surveillance, which the USA has been conducting en masse since at least 1945.
