Just asking. The whole reason uniforms were put in was because of the way the students were acting. So lets recap:
For ALL of season 10 before the uniforms all anyone was doing was breaking rules, and also you hear Mr. Simpson say how test scores have been dropped. Let's see here.
A kid was tied to a flagpole, a teacher's car was keyed, a pig was brought to school, there was cheating on schoolwork, a transgender student was bullied and thrown into a door, gay slurs were written all over by owen, plus homophobic comments were often made, AND of course in all falls down, there were sex acts, and knife fights. So yeah uniforms happened. I think this was a GOOD plot device. Even though they didn't change anyone's behavior.
AFTER uniforms were added:
Pornography was sent around, there was a fight, the dress code was often IGNORED, there were secret parties, students were getting high, students were spreading lies about dances, there was bullying, a student crashed his car, transgenders were still slanderized, MORE people were getting high, there was a student stealing girls' underwear, illegal poker games, ANOTHER shooting, another car accident, someone covered the cafeteria in aluminum foil, MORE people were getting high, there was MORE bullying, and more fights, some more cheating, and just because ONE dance goes great, the uniforms are taken away.
Now after the uniforms are abolished:
People are getting drunk at parties, the school president intentionally sabotages a pep rally video, the roof garden is trashed by unknown offenders, fights between students are STILL continuing, people are drinking at school, people being drunk during school is continuing (Clare. The last to do it was Fiona), Protest about a school play erupts, a tenth grader jumps off the railing and breaks his arm, money is stolen from the school which led to a police investigation, and a kid was intentionally locked inside a room so he couldn't participate in the play.
Don't get me wrong, I'm glad uniforms were abolished. It feels like the old days to have everyone wearing regular clothes again, but Uniforms really came and went, and without changing many of the student's behavior.
