[Hikikomori]

Worked in Australia. Works in Europe. It's not that hard to understand.

No murders? No. You should read about the "Nirvana fallacy".

Fewer murders? Yes. The homicide rate is 0.854 per capita in Australia (5.763 in the US) and much lower than US in most European countries (Russia being the exception).
