Uhm Harvey Weinstein?
Bill Cosby was convicted originally too but I think his age played a bigger part in it being overturned than him being rich.
The notion that rich people are somehow immune tho is complete bullshit.

They can hire better lawyers yes but lawyers can't just let you get away with any crime.
Most questionably legal things rich people get away with too are legal loopholes ( especially when it comes to stuff like taxes ).
Rich people aren't murdering people and getting away with it in spite of evidence against them that's just not happening.
