1. Get the hell out of government if you're an honest person.
2. Shrink government to the point that it is almost non-existent, so the dishonest folks who stay in government have very little authority anyway.
Huh ...
I disagree with (1) as a matter of public policy. We need honest people in government.
(2) is spot on ... most of government is unconstitutional.
My point is that even for honest people, cooperating with a dishonest investigation is dangerous. Once targeted by a dishonest investigator, one is doomed. Almost nobody can be certain of avoiding the dishonest investigator's "process crime" traps. Nobody should be expected to cooperate with witch-hunts and fishing expeditions. Yes, Mr. Mueller, I'm talking about YOU.
