Considering they need to have this kind of thing in place to exist at all, it looks to me like they've done a good job separating good and bad faith reasons for granting access to data.
What you are proposing is an insane privacy violation and facilitates law enforcement just being able to 'watch for the sake of watching'...

isn't your idea similar to what Assange is talking about? http://thenextweb.com/facebook/2011/05/02/wikileaks-founder-...
It’s not a matter of serving a subpoena, they have an interface they have developed for US Intelligence to use.
It would be unacceptable to an intelligence agency to have to ask for individual records in many cases; the list of names they're looking for would leak a lot of information. They want raw data so they can run their own queries in-house.
Same thing applies to any other provider. Western Union used to deliver actual tapes to the CIA daily. It's either done by the company officially, or by an employee at the company, usually an ex-military/government person working in the security department or otherwise placed to have access.
Sometimes intelligence agencies set up "captive service providers" who bid exceptionally low to win access to juicy data streams (Israel and phone billing...).
