Because In SG, 99% of such molest cases are not reported. Only 1% of cases are reported. Due to GAG orders most of the criminals are even protected under SG law. This case is an exception due to his trespass and molest.
Actually this guy is not alone but he is the only busted. Thats all. If he was unreported he may have emerged into politics in the near future to lead MOE, MCCY and other youth facing roles as part of 5g team.
Singapore is at its peak with such immoralities. These men will never be delighted in paid sex. They will target the vulnerable Chios.
Most of the RASF have been molesting cocks in the past without consent or approvals due to their ranks and it worked well among boys as they have a itchy asses. With repeal of 377A, men molesting men will not get reported. This may have helped him emboldened to try this out. As i have seen even chio chn girls holding hands of bangla men in public these days.
May be, he thought all girls and boys in SG up for grabs. He tried this out with girls also. But he failed. To my understanding NUS and NTU girls are rotten enough to get laid everyday and night.
Otherwise, they may have cooperated.
Lets wait and see how law of SG serve its justice.
