It is indeed broken.
That's a passive-voice way of saying it, concealing the ones who broke it. A better way is to say that Trump has corrupted and broken the justice system.
However: the president cannot pardon a *state* conviction. So if you can get them convicted in a state court whose governor doesn't want to pardon them, you can get some traction.
(However, in fairness I must note that Trump himself is a 34x felon in New York, with no noticeable effect.)
