I definitely agree with this. I would assume that there is documentation to show that the scan was routine and above board, although probably not normally available to states and other jurisdictions. Oversight should be enough, but these days even oversight is not politically impartial. Depending on party and objective, some things seem to be given the blind eye while others are scrutinized in on incessantly.
They should inform the state afterwards. The fact that they haven’t yet communicated to the state even though the state pointed the finger at them, indicates there might be a problem.
