Sounds like you’re not flowing along. The laws don’t magically stop people from doing bad shit. Educated populous with safety nets, full bellies, and a roof over their heads stops them from needing to do bad shit to survive. In this case, this abuse/murder wasn’t a snap from this idiot, more than likely he had been abusive for years and years but because the US doesn’t have a means of supporting those who need it (daughter and wife) then they’re stuck with their abusers.
