i believe u have been to NS before..and normally, controlled
items will be sealed with your service's emblem..so if it breaks,
you will noe.. same case..if it isnt sealed, anyone can tamper..and
everyone can pretend they dunno..so this action of sealing, is to
cover your back..so you can have a fighting point about it... and
the statement is more or less of the same thing..
it will be like
I, so and so, NRIC so and so, the undersigned of this statement
declare that i will not divulge blah blah blah blah blah..
then u sign ur name below..
its a double edged sword if she blows this thing up and ask u to
sign in front of her or your mutual friends..u can feign to be
under duress so u wont be pressured to sign..but if u refuse, it
can also mean that you are guilty and gives people the impression
that you have already divulged alot of things to other people..
