That is incorrect. Soldiers in the Army have a implicit fourth amendment protection on all US Army data systems. To overcome that some data system owners require a signature on a policy statement that allows unrestricted monitoring. Those are often called user access agreements. I have been told the Air Force operates in the opposite. I am not sure what any of that has to do with state government access. From a legal perspective state government intrusion of a federal data system for evidence gathering is equivalent to a foreign nation. The federal government will happily share this information provided the proper administrative authorizations, but there is no unrestricted access.
