So what kind of answer are you looking for?
The Emanuel family, is like talking about the Bush family. They have their hands in a lot of shit, whether it was done "legally" or not... heads will turn, because of the actions, power and influence they wield(ed).
"A mayor"... Mayor of Chicago is a big deal, buddy.
People can talk about Russian fighters and promotions and their connections to shady people. But will totally ignore the UFC's now extremely shady backers.
There's levels to power and connections, and not all of them involve blood. The Emanuels, like the Bushes, have blood on their hands (gang & police-violence in Chicago, Israeli/Palestine violence) and they have a huge influence on public opinion via Hollywood.
You can't just say "Welp, that's his brother or father, not him" and dismiss the whole thing. Is that how Jeb Bush is relative to his father and brother? I hope not. People should be scrutinizing.
