Thanks for those numbers. Singapore's (official) homicide rate has gone down even further in recent years, but maybe the others have too. (edit: never mind; my memory/googlefu is failing me)
A nitpick: Germany (and many other countries) don't really have free speech because of Holocaust denials laws; the laws are written rather broadly [1]. But sure, it's less onerous than in Singapore.
