From BKK post:

City Hall is ushering in a culture of whistle-blowing by offering cash incentives for informing on those who violate public spaces -- for example, motorcyclists who tear along pavements -- but fears are mounting it may promote vigilantism and could spark violent confrontations.

The Bangkok Metropolitan Administration (BMA) measure, which took effect when it was published in the Royal Gazette on Aug 11, promises those who report violations on pavements, ditches, canals, rivers and other public areas 50% of the fines meted out.

The regulation takes its cue from Section 51 of the 25-year-old Maintenance of the Cleanliness and Orderliness of the Country Act (1992) which states that "a person witnessing such violation is an injured person under the Criminal Procedure Code". The local authority is therefore within its jurisdiction to offer financial compensation to the injured party in the form of a reward, according to legal analysts.

The only condition: They must submit evidence to support their claim in the form of a photograph or video clip capturing the wrongdoer red-handed, making this very much a post-smartphone legal reform ...
