In US, you can be rich and get away with a lot of crime and crookedness.
If Trump does go to prison, that will make quite the news.

That’s one way to look at it. Another way is to note that they’ve done a real good job of limiting their potential future options. They get to remain in power, or be exiled and live in hiding, or be dead? They’re unlikely to resign and get to live a quiet retirement, just as they’re unlikely to be jailed by their opponents?
