Why would a mob wannabe kill a boss? Not only ending his mob career before it starts, but giving himself a certain death sentence to boot. You'd think it would be the other way around, that he would kill someone who disrespected Cali, like the kid in Mean Streets did.
I still think it's the niece.
The MAGA stuff, well, let's be honest, it's not like this is totally out of the norm today.
