The law should be applied in the same way without regard to the identity of the person.
This does not mean that everyone is treated the same by the law. Criminals SHOULD be treated differently from non-criminals.
In my humble opinion, Donald Trump is a career criminal. He has broken many laws. Before he was president, during his presidency, and after. The law is finally catching up to him. Of course it is going to treat him differently from people who aren't career criminals.
I would argue the legal system has given him a lot of breaks. Just to cite one. The investigation that Bragg dropped into his business' corrupt practices. This would have been a criminal case against both him as an indivual and his business as a corporate entity. I believe at least one prosecutor resigned in protest against Bragg's decision not to proceed.
