Public space is precious, but I’d just like to make it clear for the casual HN reader that suggesting “Singapore-style” punishment for antisocial behavior implies a pro-caning stance. Caning is a violent, abhorrent, and cruel practice that violates the fundamental human rights of the convicted person. It leaves the victim of state violence with permanent scars and long-lasting trauma. Time and again it has been shown that capital punishment is not any more effective at preventing recidivism than rehabilitation or compulsory community service.
If you want positive, lasting change, you have to start at the start, modeling positive social and emotional programs in public schools and community programs. Our society is only as healthy as the core beliefs that are willingly held and practiced by its population. Raw state power through fear and intimidation does not change people’s minds as much as widespread belief about what is inherently right and wrong.
