Re: Kind of what I said a couple weeks ago.
On the other end, probably the NSA doesn't want to lose some of its power and budget. If a court order is enough to access a criminal device, the NSA will lose some power, and may find difficult to assert it needs to access *any* device. It could be also some internal fight among three letter agencies, the FBI may not like to be forced to ask the NSA access (and be told only what NSA allows...), while the NSA may not like the FBI uses some information in public trials, and may prefer to keep everything secret as it usually likes.
