It's not about being realistic, it's about finding out what sort of information Google retains about its users. Low-profile cases are the best times to test these sorts of fishing expeditions because attention and resistance to teh subpoena will be low.

In other words: The FBI doesn't care if they actually get the information in this case; they want to know if they'll be able to get such information in future, more important cases.
