Earlier quoted context omitted.
Intelligence agencies' very role is to break laws.
That's not true at all. Intelligence agencies can't just do whatever they want. They are beholden to the people just like every other government agency. They can be granted power to do things that ordinary people can't, but that doesn't mean they are above the law.
The government doesn't want intelligence agencies reined in by anything but American interests. They want those agencies to be free do commit whatever evil is deemed necessary to further those interests, laws and Constitution be damned. The NSA is still spying on everyone. The CIA still runs torture camps around the world. Nothing changes. Snowden didn't change anything. Assange didn't change anything. Wyden isn't going to change anything.
The ability of the American people to hold their government to account in any meaningful way is a facade. Americans live under the oligarchy of corporations and the military industrial complex, not any kind of functional democracy. The American people, despite their guns and breathless evocations of the Founding Fathers, are not in control.
