Truthfully, not many do, unless you're involved (even then, usually if you're Chinese). Like I said, it's a hard argument to make that it's a 'problem' per se because most of the criminal activity occurs outside of Singapore's borders. The integration with government, law enforcement, etc. is so complete that it's barely even criminal activity any more, just the way things are done.
Trace these ****s and their activities back to HK and the picture changes dramatically. Relative to other organised crime, info is scant, second-hand, etc. Informants with detailed info are incredibly rare so the true extent of activities is assumed rather than known for sure. Everyone is paid well and they're just too good to make mistakes which can hang them.
EDIT: I would discourage anyone living there from asking about it, tbh.
