That's very typical nowadays. It's different from my experience of a couple of decades ago. With a serious offence like that, those individuals would probably have been held in custody for some time, if not until their trial. It is commonplace now for individuals to be released back into the community.
I know there's a lot of reasoning behind that given how being in custody may impact the individual, but I think there's a wider argument about the harms that society as a whole faces when some of those individuals—particularly career violent criminals who for decades have committed severe violent acts—are released into the community again. The next victim will suffer potentially life-altering injuries trying to protect their property or when they're minding their own business.
It's extremely disheartening. Definitely, over my almost 30-year career, it's the most disheartening thing I've seen—and not because I want to see people locked up. It's because I want to see society protected from people who actively want to do harm and ill against other individuals. From my personal perspective, it seems like a lot of the tools and processes that used to protect many in society have been reduced or stripped away.
