Judicial rulings can make surprisingly entertaining reading in a bland sort of way. Especially the polite, indirect ways they go about telling the losing party that they're basically idiots. I even learned a new word, "improvident" (which it would be to extend the Good Faith exceptions to completely invalid warrants.)
On a more serious note, I do have a certain amount of sympathy for the government's argument that there needs to be some way to obtain a warrant against a computer hiding behind Tor, but it doesn't sound like they made their best attempt here, not going to the right kind of judge. And in any case, they are bound by law as it stands, not what it should be, just like the rest of us.
