Final answer:
Information that no longer requires national security protection should be Declassified. Declassification makes the information publicly accessible. The Supreme Court allows the press to print classified material selectively to prevent compromising national security.
Step-by-step explanation:
When information, in the interest of national security, no longer requires protection at any level, it should be Declassified. Declassification allows for the transfer of previously restricted information to the public domain, making it accessible to all citizens. This process differs from destroying, archiving, or encrypting information, which would either erase the information, keep it stored for limited access, or encode it for security purposes, respectively.
According to the Supreme Court, the right of the press to print classified material is partial, meaning the press may print classified material only if it does not compromise troops or covert operatives. This reflects the balance between the need for public access to information and the protection of national security interests.
