Poor mental health / disregard for mental health issues in general, and crime, are linked more than most people care to admit. The systemic failings are occurring long, long before the stage of someone being in prison. That applies across the board. People are looking to solve problems in all the wrong places.

Of course, as always, it's lovely to see all of the outpourings of empathy being offered. "They shudn't have did a crime then lol". But that of course is the majority opinion of simple simon public and so we come nicely back around to the reasons that these systemic failures are happening in the first place; people have little or zero desire to understand, much less care about, anyone who "isn't like them".
