check IC is for the safety and protection of the public.
as describe by scenerio above, it is a way of detering crime,
vandalsim and gang fights.
and at same time catch suspect on the run.
eg, a group of rowdy youth adults playing BB , singing or guitars
at void decks , chases each other and small fights. residents
complains, police come check IC, one found to be drug offender on
the run and missed reporting. search all of them found drugs and
knifes.
glue sniffing is most common.
imagine what will happen if they tooks drugs and molest , robbed
any of the residents coming home. and if no IC scan, then the CO of
the NPC will be in trouble. by the way once the IC is scanned, i
believe it is recorded,
they always hang out together. you see one , you will know the
others are somewhere nearby and up to something no good.
the best way to combat neighbourhood crimes an disorder behaviuor
is residents alerting police.
please when handling IC to officers, do it in respectful way , and
stand up first unless told otherwise. and show manners. If not they
can treat you using the same procedure as hooligans or gangster.
especially if a call is from the resident with certain
connections.
anyway it is wrong to disturb residents staying there with night
activities. next time you disturb someone , and that someone knows
where you stay , he will go and disturb your family members at your
unit. eye for and eye.
