And the NYC Department of Education will defend this how? N.Y. Daily News:

When you gotta go, you gotta go, but it’s not that easy for the 634 students at a downtown Brooklyn high school.
For the past month a single toilet inside the nurse’s office at Science Skills Center High School was the only one open, forcing students to endure bladder-busting waits whenever nature called.
The school wasn’t at a loss for loos, though. Administrators kept four other fully operable bathrooms locked up to prevent kids from misbehaving and getting violent in them, according to staff and students.
Only after the Daily News inquired Wednesday about the lack of latrines did administrators open two other bathrooms.
Kianna Cole, 16, an 11th-grader from Mill Basin, said having to use the filthy toilet in the nurse’s office was worse than getting a month’s detention.
“It was awful – and not just the smell or the line. It was the pee all over the place and the terrible plumbing,” Kianna said.
Flush with rage, she started a petition last week calling for more commodes at the Flatbush Ave. school. Kianna got more than 200 student signatures, but didn’t have a chance to deliver the petition before her school opened more cans.
