They just need plausible deniability, which is trivial to manufacture at this stage of the game.
"Oops our black box went off the rails. We'll add better logging and alerts next time around."
"Oops our black box went off the rails. We'll add better logging and alerts next time around."
Plausible deniability is “I was away from home when my gun was used to murder someone.” This is, at best, “oops, I pulled the trigger accidentally.”
You're right in theory, but in practice this hasn't been the case, at least so far.
