If I'm not mistaken, they've sort of tweaked the definition of "interception" too. The game plan is to capture everything and then it's 'intercepted' when they actually listen and analyze it.
That was the talk at Defcon, I didn't do enough follow up to find out but it's pretty open that the new Utah data center can store every American's phone calls, emails, .. everything for a century.
If you can slip that through whoever it is that protects us, there are some corner cases. Say we do rub out a terrorist cell that does a successful attack (20 years after this database is running,) could you then mine that database to determine if your AI that finds terrorists works? If I was training up voice finger printing algorithms and such, you have an incredible dataset and there are likely other signals coming in to help populate it (maybe the census? say you're training something that detects Arab accents)
Never mind the fact that it's so huge and so much data that 1) is has to be online and 2) all intelligent queries will be given to AI/Google like software agents to find. Could a future president query the database to dig up dirt on an upcoming election opponent? (He's the president right?)
