> One can't disobey "conventions"

You are playing a semantics game. Replace disobey with ignore, and the intent is the same.

> you can't be disobeying if you're the boss and decide who gets tried and who doesn't

The United States is a constitutional democracy, not a fascist regime. In the past, presidents have indeed disobeyed, and one was consequently impeached.
