It's about trawling, not about process.
Your are not telling me that any remotely compent national security agency does not have a good few moles embedded in telcos, Google, Facebook etc. If they want data on any single person, I bet they can get it in minutes without going through any formal processes whatsover.
The only purpose for a dragnet this big (and this leaky) is to hoover through vast quantities of data to see if anyone is doing anything wrong - or, even better, to ensure that when the government do want to go after someone, there's a previous record of them having done something "wrong" like watching internet porn or visiting suspect sites.
I'm sorry to keep saying it, but we used to be prepared to risk nuclear war to avoid ending up in such a sick, surveillance society.
