Singapore Computer Crime Laws OK Preemptive Arrest
^^MAg^^ points to this Reuters story on CNN which begins "Ultra-strict Singapore has passed some of the world's toughest laws against computer hackers and virus writers, allowing police to arrest suspects before they strike, official documents show."
You see, chewing gum per se is not illegal, but the sale of chewing gum is. That's an important distinction; it means you can, for instance, legally import how much ever chewing gum you want into the island, only that you can't sell it. Been like that eversince chewing gum was legislated, mostly as a way of preventing adolescents from sticking left-over gum between the sliding doors of Singapore's ultra-efficient metro system, the MRT (and hence jamming them, causing systemwide disruptions).
Btw, even that fig-leaf is now mostly gone. The recent Singapore US Free Trade Agreement stipulates legal sales of chewing gum that can be used for "medicinal" purposes through registered/licenced apothecaries. So don't be surprised if you see chewing gum (although perhaps not bubble gum, if you get what I mean) being sold in a pharmacy on Orchard Road or something.
(The locals that I know call this the "Wrigley Amendment" for some reason. Wonder why, hmmm.)
More than mere navel gazing.
