So...is the absence of classified evidence itself a classified matter?

[MedusaX]

6. Significance of any piece of evidence is subject to change over the course of the investigation

evidentiary material exists
It remains Classified until such time as it is introduced into to evidence in a court procedure or is officially de-classified for whatever reason.

The evidentiary materials that may have been initially thought only to represent reasonable/legally permissible acts...

May have taken on a new significance, relative to illegal acts, as additional evidentiary material was obtained and reviewed....


Until such time as a final ruling has been made, as to the criminality of the acts evidenced by those materials, it is impossible to confirm or deny that the materials can be conclusively deemed sufficiently indicative of any given criminal act.
