The whole thing is amazing (that this is the germ for impeachment) but here’s a relevant snip:

“Shapley described that the FBI obtained and confirmed the device identifier before they ever met Mac Isaac, on November 6 (though perhaps Mac Isaac only referred to other identifiers needed for the subpoena).

Nevertheless, this discrepancy is important for a number of reasons, not least that if the FBI looked at all closely at the returns on a subscriber subpoena to Apple, it should have raised significant alarm that someone was trying to hack Hunter Biden. But if they didn’t obtain this information until the day they obtained the laptop, then they couldn’t have reviewed the subscriber data very closely in advance. That negligence might, in turn, amount to negligence in missing clear signs that the then former VP’s son was being hacked.

As Mac Isaac describes it, it was not until Agents arrived at his shop that they told him they were going to seize the laptop with a subpoena rather than imaging the laptop there at the shop.“
