I think it may have helped establish an unwritten tradition of not going after the previous administration’s people lest it someday be done to your own people, but I think Mr. Trump, with his well known propensity to have a long memory and hold a grudge, will do the right thing and not try to bury the truth for the sake of keeping the peace. I hope not.
The use for that goes away when a party to it is not just erring, but evil.
