It's a compromise either way lah. If you inform people, security
will definetly be beefed up to an unrealistic standard.
If you don't well, it's darn realistic but you are also in the deep
end if you're discovered.
Honestly, if I had a team of commandos/NDU/SOF/SWG, I am pretty
darn sure I can penetrate almost any base in SG with relative
impunity.
