AITA for telling my (now ex-)friend to remove a facebook post?

This was several years ago (as evidenced by the part where anybody still used facebook), but somebody I knew from high school (24F ballpark, let's call her Kim) went on fb bragging about having gone to a girl's house, broken into said house, and beaten the girl up. The justification for this was that she was a homophobe and bullying a friend of Kim's, who was a lesbian (let's call her Jane).

I commented on the post like "buddy. buddy you know there are cops on facebook, right??? and that you've just admitted publicly to breaking and entering and aggravated assault and battery, RIGHT???? you might wanna delete this post before cops find it and you get very arrested" and she FLEW OFF THE HANDLE

Kim started screaming at me about not being supportive, that she'd been in the right, that I was defending some homophobe I knew nothing about. didn't seem to matter how many times I pointed out that I don't care if she beat somebody up; I care if she gets arrested from posting evidence like an idiot online. I'm trying to help her cover up a crime; what more proof of friendship do you WANT? anyway Jane decides to pitch her two cents in as well and say how grateful she is that Kim beat someone up on her behalf and that I should shut up since I don't know anything about the situation and how bad it was getting (this was never expanded upon).

after being blown off and screamed at for having THE NERVE to tell them self-incriminating evidence is still admissible in court, I told them both they were idiots and would honestly deserve the arrest at this point of the "play stupid games, win stupid prizes" variety and blocked them both.

side note that Kim's boyfriend was a drug dealer at the time and if the cops searched her house, they would almost certainly find evidence to drag him down with her, so that would really suck for him, the poor bastard

I'm pretty confident I was right and if what's-her-face reported the incident to cops - if indeed it ever happened and Kim wasn't just making shit up for clout(?) on the internet - it would be a slam-dunk conviction, and that friends look out for friends when cops coming sniffing, but given how multiple people all gave me shit for saying so, was I the asshole for jumping right into "you're an idiot for posting this online" (not my phrasing, I was nicer about it but like... yeah that was the gist)?
