It's called "chain of custody."
If an inventory of what was seized under a search warrant, fully documented and signed by the turds in charge, and fully covered time-wise right on through to the inevitable court case was not done, videoed, and documented, DOJ is ****ed. They have nothing. From the sound of things, the lawyers on the ground at MAL weren't ALLOWED to witness the search, much less what was seized. What was planted? The lawyers could make hay with that.
The lawyers were initially DENIED the right to even review the search warrant, but then the turds in charge thought better and ALLOWED them to see it (but the lawyers could not retain it). The accompanying affidavit, which customarily provides probable cause, is sealed and would not become unsealed until a judge allows that action later in a brief to the court.
There is so much wrong with this process that even a non-trained person like me can see the issues. Trump will emerge the victim and his supporters will glom onto that, and no doubt attract others.
Merrick Garland is an idiot. Assuming he authorized this pile of shit, he just revealed how stupid he really is. Thank God he's not on SCOTUS.
But in a very real way, this issue has no doubt galvanized freedom-loving Americans, whether or not they're MAGA types, and you can ****ing well believe that the turnout in November will deliver a CRUSHING blow to the turds in charge.
