The "Oh, it'll be okay, you can go to court and the judge will fix everything" attitude is out-of-touch and callous to the harms people endure even under the best circumstances. Kinda pisses me off. Would like to know how long the professor would be willing to sit in jail to have his day in court.
This all gets back to how SCOTUS has screwed all of this up and gotten it completely backwards: we in fact do want Presidents to be worried about getting second-guessed in the courts and at the polls, and to worry about being prosecuted and/or impeached. Immunity should be limited if it even exists.
