Hold on a second. I understand what you are trying to tell us, but you cannot possibly proceed on a case-by-case basis when deciding whether to allow access to a document or not. You must have rules that have been established to determine what documents concern national security, personal information, and so on. There must be some sort of information release mechanism. You cannot use the case-by-case approach each time and make decisions arbitrarily. You must have a mechanism that has been pre-established or prescribed.
