You don't need years to look around and see that (unlike much of the US) there are no homeless addicts, fare evaders, or vandals on the transit in Singapore. (Or, for that matter, murderous psychos with dozens of prior arrests.)

Logically, therefore, they have superior crime policy we should learn from - nothing to do with culture.

But you are wrong. It is entirely possible that the population of Singapore would act exactly the same with a lax policy.

I live in Switzerland. There is no public caning for chewing bubble gum here.

Yet it is an extremely nice place to live in.

I have also lived in Dubai where there is sharia law. Also a nice place for most people

The more good solutions there are, the more shameful it is if we cannot adopt any of them.
