The article emphasizes that he will not get out any time soon and may spend the rest of his life in a hospital, but given how fucked up our legal system is, I have no faith that this will happen. And at the end of the day, why does it matter if he's insane rather than evil? He's a clear danger to everyone around him either way, and his hospitalization is going to cost honest, hardworking people tons of money that no one can afford right now. I think the only reasonable thing to do is say that, for the health of everyone around him, we need to swiftly execute him. And I'd guess this would have been common sense 200 years ago, but this country is under foreign occupation and being manipulated to let insanity like this continue.
Notably, the article doesn't specify what exactly the insanity defense was. If it's drug-related, execute him. If it's some genuine freak-occurrence psychosis, maybe give him a second chance. But if he's running through the streets shooting into random cars, something tells me that he's not an upstanding citizen to begin with. Plus, I don't think it's a coincidence that a black man attacked Asians, blacks have hated them for a long time and see them as easier targets than whites or hispanics.
