I'll wait to see the actual motion, but it seems reasonable that they would want the names of staff redacted to prevent them from getting death threats from people that equate them to leaders of the hitler youth.
Equating them to the leaders of the hitler youth may be an extreme interpretation but is not threatening.
My understanding is that the two prosecutors in the Aaron Schwartz case have reported receiving threats -- One email gloating at doxing him, one postcard of a guillotine and one of them had their facebook account hacked. I've always assumed that people in high profile jobs like that receive threats on a regular basis, and that given the unpredictability of 4chan / anonymous that the number and types of threats were unexpectedly tame.

So it would appear that the names are already redacted
But the faceless bureaucracy is the problem. If people can make stupid decisions then not take responsibility because someone somewhere on the internet said something dumb then these problems will never get fixed.
