Unlikely to be secret society as they would not be so coward to kill children.

You are Wrong, actually last time Secret Society is REALLY ruthless thus this why common folks scare of them, as they go around collect protection money , etc even Police also not scare. Is later Gov implement tougher law on SS than at least under control.

What I know from my parents they claim 50s, 60s it the most happening one SS gangs fights etc later LKY become PM he implement law on it , etc force quite alot Gang leader flee to MY or further up to Thailand etc but still some are active and ruthless despite tough law on it. 70s still got SS a lot active is come Early 80s no much
