Good for her! When I was in 9th grade, our new principal let everyone know that the saggy jeans look was totally out; I went to a school with a big gang and drug problem. She went out and bought a bunch of neon pink jump ropes, and if she caught you sagging, you had to tuck in your shirt and wear this HUGE neon pink jump rope like a belt, and were not allowed to take it off until you left school property.
She was one tough lady, and took no crap from anyone. The year before she came there were 2 stabbings just off school property, 1 stabbing on school property, 10 drug busts, and gangbangers hanging around campus. When she showed up she instituted random sobriety tests, random searches, made sure the cops were a constant presence all the time, random locker searches, the works. She let the teachers no that they were not to take any crap from any kid, and punished disrespect severely. She also raised private money for music programs and field trips, which we didn't have money for, but you could only go on the trips if you were in good academic standing and hadn't been in her office for at least 3 months. A lot of kids complained about it, but in 2 years the gangbangers were gone, almost no one was sagging, and the campus was pretty much drug free.
Of course, Los Angeles being the liberal, loving town that it is, she was fired about a year afterwards because some parent complained that her poor son, who was in the Crips at the time, suffered irreperable damage from having to wear a pink jumprope around all day. Figures
