If it were that simple why didn’t they do it?

It is that simple, the Jack Teixeira case shows how qiuckly and how simple it is to get a fucking warrant and get the documents out of the hands of people who have no business holding them.

Once you have the documented evidence recovered from the warrant it's incredibly simple and iron clad to show that trump violated the law. having those documents is itself all the evidence you need.

as for what laws were broken That to is incredibly simple, and the simple fact of him having the classified materials after leaving office is iron-clad proof of his guilt. the text to save you click:

(a) Whoever, being an officer, employee, contractor, or consultant of the United States, and, by virtue of his office, employment, position, or contract, becomes possessed of documents or materials containing classified information of the United States, knowingly removes such documents or materials without authority and with the intent to retain such documents or materials at an unauthorized location shall be fined under this title or imprisoned for not more than five years, or both.

(b) For purposes of this section, the provision of documents and materials to the Congress shall not constitute an offense under subsection (a).

(c) In this section, the term “classified information of the United States” means information originated, owned, or possessed by the United States Government concerning the national defense or foreign relations of the United States that has been determined pursuant to law or Executive order to require protection against unauthorized disclosure in the interests of national security.

Do you think they were conspiring to help Trump? Do you really think they just said “I don’t want to do that today, let’s put it off for another time”?

Their stated justification for their actions were "to avoid appearing political". Which, given the blatant guilt (you saw the news-crew videos of the FBI agents dragging out the classified materials, right?) inaction is itself also political.

Any one with even so much as a single half-baked ethics training class under their belt would know that the way you avoid accusations of political bias isn't to change how you do your job- it's to do the job in the same way that you always would; and to document the shit out of doing your job that way for transparency. Sitting on your ass for two and a half years is inherently political when you would not do that for literally any other subject imaginable.

But Trump has been able to avoid consequences for everything he has done so obviously it is not that simple to prosecute him.

Because chucklefucks like Marrick Garland can't be arsed to do their fucking jobs.

I dont know why it is so hard for you to see that.

Because you don't want to
