Even if were to accept those things as true, stating things which are true is not the only indication of good faith. It is a widely used tactic to use rules only followed by one side against that side. Example (feel free to replace "I" with "my supporters" here): If I believed that anything I did in my interest was acceptable, but you believed that you were bound to work in the interest of the public, then I could claim that you giving your son a government job was corrupt and you would be bound to defend that, whereas if you claimed giving my son-in-law and my daughter government jobs was corrupt I would just ignore you.
