Nervous? - NIPR.mil Visits my blog

Hmmm... Just checked my visitor stats to my blog and today, the military has been visiting.  They did a search on ""winter soldier" hearings transcripts copy" on Google. Now, I am not very paranoid, but when I did a search on nipr.mil, I found this:

""Nipr.mil is not a single domain a but a hush-hush web proxy that acts as a gateway for hundreds of U.S. military domains in order to hide their identities. It was established by the Defense Information Systems Agency (DISA) in response to a memorandum (CM-5 1099, INFOCOM) issued in March 1999 by the Chairman of the Joint Chiefs of Staff, calling for "actions to be taken to increase the readiness posture for Information Warfare." "Uncontrolled Internet connections," the document says, "pose a significant and unacceptable threat to all Department of Defense information systems and operations." "

Now, wouldn't they already have this info?  Why would they be looking at other sites for the info?  

Well, in the end, probably nothing, but in the climate we live in, I can not help but get a little nervous when I see them there.
