The mealy-mouthed explanation, as if only passive, technological glitches occurred by themselves, rings of falsehood. In a justice-based Justice Department, there would be a full-court press to investigate who is responsible for these “glitches”, exactly how, when and why they occurred. I don’t buy an accidental loss of data AT ALL. Especially when you consider that the exact time frame covered is at the heart of the time period when a conspiracy was apparently being executed to overturn the results of an election.
Yes, it is not believable. If they put in place a new system, and in a week or two of testing or roll-out it was found to be missing captures, that would be understandable. But it went on for 5 months, and they didn’t know it was missing doing its backup job all that time? Nope. You are too incompetent to hold your jobs if your story is true.
