Material evidence is mysteriously destroyed after the event; no substantial physical evidence remains and media flatlines on followup
- Debris is quickly carted away
- Suspect buried at sea / burned alive
- Tapes are conveniently non-existent, 'destroyed in the incident' and / or "classified"
- Witnesses 'suicide', have accidents or disappear
- Mass media censors, blacks out and 'brainfades' on any questioning on any of these matters
