You are playing with me again. You are too smart to give that crap more than a passing glance.
I give it a 10% probability of being true. I recall reading an article some years ago about Trump sending different documents to different people so that when the document leaked to the press, he knew exactly who leaked it.
The larger problem with this being a setup by Trump is that it would have been mostly inconceivable that anyone could predict the FBI would have the gall to make such a raid against a former president, especially on so slight a pretext as they used.
However, the safe did end up being empty, and from what we have seen of the description of the things they took, it certainly doesn't look like they found what they wanted.
And now Trump knows someone who knew about the safe (6-8 people) is a rat.
Maybe it's luck, but Trump is coming out of this thing smelling like a rose.
