Court is to Trump like sunshine is to a vampire. If he ever made a personal appearance in court he would perjure himself in the first 10 minutes. That's why he has lawyers pay everyone off, so he doesn't have to go to court and testify. But in criminal cases, you have no choice. Sure, you can take the 5th, and his lawyers would insist on that. But get Trump on the witness stand and his narcissism would kick in with a long crazy justification for every charge.
Personally, I'd like to see him charged for walking in on the naked teens in his pageant. That has to be some sort of sex offense, like walking into a high school girl's gym to watch them shower. Some states have removed their statute of limitations on sex crimes. He has admitted this in public and there are lots of witnesses. He justified it because he owned the pageant.
