We did not prosecute Nixon, but we did prosecute his enablers (Haldeman, Ehrlichman, Dean, etc.). Because of this a generation grew up knowing: If you commit crimes for the president, he will not go to jail but you will.
That is the lesson that the next generation needs to learn. Ignore Trump; prosecute his corrupt enablers.
“There is a social cost to not pursuing potential criminal cases. But the alternative is arguably costlier.”
