All these gangsters encouraged to "move on" after they did their dirty deeds for the PAP. URA and other stat boards use a lot of these gangsters to create "PAP Lightning Strikes", and burn alot of the old ghettos so as to make way for developments. Otherwise, forcing those residents to leave would have caused multiple riots. Since these gangsters are witness and sooner or later a few of them will talk and implicate the PAP in these acts of arson, the PAP just give them passports and quietly let them go with the promise not to chase them. A lot went to US, particularly in San Fran, where they join gang with HKG triads. Others went to Europe. This article from shit times don't indicate that Denmark will not extradite this guy back to singapore for murder because they do not have the death penalty. Neither will they extradite him because he could get caning for a lesser crime, and they don't have corporal punishment. In the end, PAP govt just bury this since they know the Danes will not let him go no matter what evidence they have on him.
