This is only true for dumb people who can't think beyond their basic instincts. Settlements happen all the time with non-guilty parties, both in criminal and civil cases. That's because our justice system is wildly expensive. For rich people, it's much easier to pay to make something go away, even if they're innocent, than having to deal with:
A) potential years of litigation which would probably cost more than settlement
B) have the media spinning things because they love sensationalism even if it's allegations with no firm evidence
Frankly, all that we're allowed to know about this situation makes me feel that I have zero clue what happened. I really don't like Panarin as a hockey player and I want him traded, but I have zero judgements about him as a human being based on what I read here. There's things that could change that and we'll see if more ever comes out (or other events validating a pattern of behavior) but as of now making any judgements off of what we have is for small brained people.
