Its helpful alright.
Let me tell u of my coy experience. We have a sadistic PS and PC in
one of the platoon. Platoon kena tortured jialat2.
One of them called the hotline.
PC and PS got to know abt it....and they double the torture!

Since then they are afraid to do anything.
During CO talk, other platoons tried to urge the tortured plt to
tell CO. But they didnt.
Funny thing is, someone from the next coy is the one who told CO
abt the tortures. And CO launched a full scale investigations
against PS and PC.
So yeah, hotline can only give warnings? But not actions... just my
view.
