Final answer:
The statement in question is false; classified or controlled unclassified information (CUI) may not be freely shared even if it enters the public domain, as it is legally protected to safeguard national security. The press has a partial right to print classified material, restricted when it might compromise national security, such as endangering troops or covert operatives.
Step-by-step explanation:
The statement "Classified information or controlled unclassified information (CUI) in the public domain may be freely shared" is False. Once information is designated as classified or CUI, it is protected under laws and regulations meant to safeguard national security and other sensitive information. The fact that such information inadvertently enters the public domain does not eliminate the obligations associated with its handling.
The Supreme Court has determined that the right of the press to print classified material is partial, meaning that while there is some latitude for press freedom, there are limits especially if the publication could potentially harm national security interests, particularly troops or covert operatives. Therefore, even if classified or CUI is in the public domain, sharing it may still be illegal and could lead to prosecution.
It is important to understand that the protections of classified and controlled unclassified information remain in force regardless of whether the information has been disclosed publicly, and individuals with access to such information must handle it in accordance with all applicable guidelines and laws.
