Obviously, it's not because Shallow's students are more lascivious than their peers, but because Principal Brenda Champion (haha) has a "zero-tolerance policy," as the school's PTA president told the paper.
The Post has the lurid details of sexting:
Some Shallow students are deep into sexting, several told The Post. [Deep? Ew, why is the Post always so gross.]One girl said a boy classmate pressured another girl into texting him a picture of her breasts. The photo was forwarded to other students.
“Yeah, I’ve seen it. It was her boobs,” one girl said.
