Singapore does not mess around with this sort of stuff. The rule of law reigns supreme.
The city/state reminds me of that STNG episode where, while visiting a spectacularly beautiful planet, Wesley accidentally trips in a garden and accidentally smashes a plant.
They find out why everybody there is so law-abiding. The penalty for his action is death.
Singapore has not crossed that particular line, but you commit even minor infractions at your peril.
