Where is her anger with MTG for interrupting him when he was trying to say her name?
She's probably fine with that. Biden's actual policies at the border are the reason her daughter is dead. She knows that and was probably glad that MTG called him out.
He botched the name, in part, because he went off script, and because "Lincoln Riley" is a prominent FBS Football Coach, so I cut him a little bit of slack there. But then he went off script, and then he called her killer an "illegal" and began to hint that there were lots of "illegals". That, for me, was the high point of the night; to see MTG absolutely OWN Biden. If he were in control of his emotions, Biden could have stuck it back to MTG and owned her in the exchange, but he let his anger get to him and he couldn't differentiate MTG from Cornpop and he began to say stupid things. Not that I minded him calling these illegal aliens "illegals". No person is illegal; I'll agree with that, but these people are illegally here. And a lot of these people have criminal lifestyles. (Venezuela is emptying its prisons and mental institutions and we don't have an agreement that they will take back the people we deport from there.) But it was comic relief to see the worst people in America all offended and prepared to lecture Biden and the rest of us on decorum.
As for Laken Riley's mother: Just who is anyone here to criticize who she gets angry with. She's not a political figure, and she didn't ask for her daughter to be a subject of the SOTU at the way it came out. But her daughter JUST DIED and she was murdered by a sadistic killer who wouldn't be in the US if Biden had been enforcing the laws. If she decides to speak at Trump rallies or the Republican National Convention, then she's opened herself up to fair critical feedback, but we're not there yet.
You're aware that illegal immigrants commit crimes at much lower rates than American citizens, right?
