It is perfectly possible that Trump is a despicable person and a serial abuser, and that the American justice system is nonsensical at the same time.
Granted.
Countering Rushy's point of "the system is insane" with "but Trump bad" is not really addressing what he's saying.
But, he's not just saying "the system is insane", he said it was a "modern day Salem witch trial".
Now, I'm hopeless at history but witch trials are, in general, a byword for women being convicted just because someone accused them of something ("she turned me in to a newt!") with very little evidence. That absolutely isn't what has happened here and it isn't how the system works.
You can't just rock up to court, say Trump did a thing and collect your cheque. You have to provide a level of evidence such that a jury will believe you. You have to, for example, evidence that you've met Trump. And done so in a context where he had an opportunity to do what you claimed. It helps if you have some witnesses who can corroborate - in this case she had 2, one who said Trump did a similar thing to her, the other who received a phonecall from the lady in question right after the incident and testified to how distressed she was. So this isn't her just saying he did a thing, the jury saying "well, Trump is a piece of shit so yeah, he probably did". She provided a level of evidence high enough that the jury believed her.
If you did just rock up to court making false allegations and it was clear you'd never even met Trump then surely he'd be able to counter-sue you for libel or defamation and you'd be taken to the cleaners. While we are here - Trump basically convicted himself in this trial. If he'd just shut his trap then he'd never have faced criminal chances. So he can fuck the fuck off.
