I don't see anyone in that article who holds the views you describe. There aren't even any opinions mentioned in the article, liberal or otherwise. Did you share the wrong link?

It's an article about criminals trying to game the system in court: the disingenuous insanity plea has been a feature of Hollywood court dramas and other movies forever. There's nothing new here.

Here is a nice quote from the article though:

> “This is such a fraught area, and it’s prone to hype and overstatement,”
