Seriously, i still dun see e rationale in tis rule. Since the
sch so kaypoh, then might as well set the rule as: "NO LOITERING
WHILE YOU ARE A STUDENT OF SASS, WHETHER U ARE IN ATTIRE OR NOT."
If students has been smoking or badly attired, gaming in arcade or
behaving badly in the public, it's legit to punish the
students.
I've a suggestion. Try violating this rule for
once. While going out, look for chances to help ppl out. I dunno...
catch some thiefs or wadever, though i doubt u're find tt much
chance in sg anyway! 
After
u get some commendations frm the police or something, and yr sch
kinda wanna busk in the same glory as u, declare tt u broke the sch
rules and be punished. Then, get a friend to report the case to
Channel 8 Frontline. When those ppl frm mediacorp start
interviewing abt u, u rant abt u muz abide to the sch rules despite
having done a good deed, and tt u felt tis rule is redundant and
punishing students for no legit reasons more than to preserve the
sch image and honor. I swear the sch will abolish tis rule
completely! 
The
character of students lies not in their action, but in their heart.
All the sch did is infringing human rights, for it's fame.
