The Corrective Work Order, commonly known as CWO, is a Singaporean law meted out to 'litterbugs', those who are caught littering in a public street.
The punishment aims to force the offender to rehabilitate and shame litterbugs in public to deter others from committing the similar offence.
Occasionally, a few who served Corrective Work Order had their faces photographed by The Straits Times and published on the front cover.
[2] Litterbugs serving Corrective Work Order usually have their faces covered with a mask or plastic bag (which is legal) to avoid being identified by members of the public.
[citation needed] However, media interest long since tailed off, and there is some evidence that the sentence may now be less effective as a deterrent to littering by the general public.
