Deleting the data would be a clear crime.
I would think the County’s Attorney’s office would be obligated to follow up with an investigation of who deleted the data and prosecute the deleters.
It is hard to parse the carefully written statements of the county election officials without more information than is readily available from public sources. However, it appears that the election officials may have moved databases from the election server to backup disk drives. It may be that they did not provide those backup disk drives to the auditors, only the server, and therefore from the point of view of the auditors the data was deleted.
From the point of view of the election officials it was just moved to another disk, not deleted.
This sounds, based on what I have seen, more like a non-cooperative election office than an actual deletion of data. It may be grounds for a complaint to the Court which ruled the subpoena valid, but it is more likely to be just more noise in a battle of sound bites.
