Some honest Cop is going to back this up several times and put them in several different safe places. It’s easy and fast as 1, 2, 3. They should have done this before they the FBI started to work on the 4 different devices.
I seriously doubt there will be any review of these emails for some time. Remember State was ordered to turn over the emails. They told the court they could only handle a few thousand a month. They missed several deadlines and still haven’t turned over the majority of the emails under court order. I believe they numbered less than 40,000. Now we have 650,000 emails and no deadline. I doubt they started yet. It took 3 days to get a Warrant. Need I say more.
