From experience I note that the blanket of silence of a “criminal investigation” is used to keep the spotlight off any politician who may feel embarrassed or called to task for something not criminal at all. “cannot tell you that” or “the investigators are looking into that now so no comment” or “I called in the FBI to look into it which they are doing”.
Watching a documentary on the Columbia Shuttle loss last evening. First thing the administrators as NASA did was issue a black out on any info from NASA on the matter. It is common practice to do so especially in a deep state matter.
Blanket blackout and blue ribbon commission to spend years investigating and reporting on recommended actions to improve already excellent performance of dedicated hard working professionals.
