It can be interesting to read some of the agreements high-end executives and technical types have with their employers or contractors. Same with a lot of business contracts. Many, if not most, have “secrecy” clauses in them. The purpose is to prevent later disclosure of trade secrets, sources of business, methods of business, etc.
The purpose is competitive. They don’t want their competitors to know all their relationships and ways of doing things.
Ultimately, every "trade secret’ the Trump organization has will be “leaked” in some manner, or simply disclosed openly as part of a critique. I don’t blame Trump for criticizing Mueller for digging into the business affairs of his companies.
Why is all of this happening? It’s happening because justice is knocked askew in the “special prosecutor” arrangement. Instead of investigating known crimes, it ends up investigating people to see if they have committed crimes, and sometimes not even crimes. Granted, Bill Clinton lied under oath. But what was that about? A non-crime; having an affair.
As Democrat Alan Dershowitz pointed out, this is Stalinist legal practice, not American justice.
Maybe Trump or somebody in his organization committed a crime, or will commit one by failing to respond fully to some interrogation. But the American justice system is about prosecuting known crimes, not boring into peoples’ lives to see if perhaps they have committed some crime or will commit one in the future under the pressure of the investigation.
Maybe Trump will be able to remain unscathed by all of this, and maybe he won’t. But one thing is for sure. No ordinary person in this country could withstand this kind of thing.
