Assuming your question is being made in good faith -
Doesn't matter how they got there - if he had just said "holy shit - how did these things get here? Of course you can have 'em back" - you know, like everyone else - nothing would have happened - even if if Trump carried the boxes onto his private plane himself. The "raid" was nothing more than the simple execution of a search warrant - which was in not even mentioned by the FBI so as to avoid making a big deal out of it. Trump had to broadcast it on every channel he could to continue his grift and keep up his victim mentality which is all he has anymore. The crime is "willfull retention" - which is what happens after you tell the government to pound sand 3 different times when asked to return them.
Put simply - doesn't matter how they got there - the crime is not returning them when asked (multiple times).
