Simple. Dont go. No one force you to go.
Go then
be prepared for this kind of cases. Police can't be everywhere at
the crowd. To save all the trouble of going to make police report,
angry that you got molested, mentally being hurt. Stay home. By
going there, you are already show that you accepted having the risk
of being molest in any kind of ways.
Just like girls who like to wear short skirt or over exposed
clothes and dont like the feeling of guys constantly looking at
them. You yourself in the first place do something that attracts
people's attention first, now you got it, why complain?
Girls... 
About anti-bangalas thread, ask yourself for those who dislike
them. Are you willing to do what they are doing? Road sweeper,
construction workers, Waste cleaner etc that the bangalas are
doing. By saying this, it doesn't mean I support what they did that
cause so much trouble. I just want to say that there are good,
friendly bangalas and what you see is just some minorities. Even if
you can accept the job they are doing, how many other Singaporean
can?
