Earlier quoted context omitted.
The NSA leverages these exploits to spy on foreign nations. That's fine, spies should spy... But it does beg the question: who's protecting our information from foreign intrusions?
Isn't that partly the mission statement of the NSA and CIA and FBI?
Defense is arguably part of the FBI mission, however they don't have the NSA's level of skill or resources. The FBI might be able to detect abuse when it gets rampant but I have zero confidence that they would discover any of these exploits themselves. The FBI is mostly cleanup and criminal prosecution.
We need an organization focused on preemptively securing our infrastructure.
