Punishments for foreigner litter bugs
For low-skilled foreigner litter bugs, I think a fine is a better deterrent than a CWO. These workers are already doing the menial jobs which have low wages. A CWO means they sacrifice some of their free time but a fine would make them feel the pinch more.
On the other hand, for professional foreign workers with high pay, a CWO would have a greater deterrent effect. (In case you do not know, CWO stands for corrective work order - for example sending litter bugs to clean up a certain place.)
Caning of criminals
Some people don't like the caning of criminals. They say it is inhuman, archaic, etc. But these reasons are not good enough for us to do away with caning. I believe caning is a deterrent. Putting aside the deterrent effect, people who committed certain sex acts or violent robberies that caused grievous harm to others should be caned.
