My brother and I had our last fist fight in our mid 20s, but neither of us have ever escalated it past that with cops or weapons or any other idiocy. We're from a part of the world where brothers fist fighting each other in their fuckin 50s is very normal. People are coming down hard on Jamal, but from what both sides have said, it really sounds like Jamal's family situation isn't as black and white as some are trying to make it seem.
To me it sounds like Jamals family has been pulling at his pockets since he became champion, there was a dispute over some minute amount of money, Jamal's brother started insulting him about how he "doesn't care about his family" or similar and brought up how he's even a bad father for not calling his daughter on Thanksgiving, as parasitic individuals will try to rectify their taking from you by linking themselves to someone else you should inexorably care for and therefore support, and it escalated from there. Just the way Jamal's brother phrased it
"I was conflicted with calling the police because I knew it would ruin Jamal's career as a fighter"
Okay, but you did it anyway? He didn't call the police to save his life, he called the police to press charges. If it's your brother, that's bitch shit, especially if you
know you said some shit to instigate it, and especially if you know it's going to put a dent in his career that
you're probably living off if he's paying your wife $300 to clean his house.
I haven't had to deal with any of it with my immediate family thankfully, but some people just have shitty family members dealt to them. I'll reserve judgement for whether it's Jamal or his brother until after all the facts are out.
