This Couldn't Really Have Happened This Way, Could It?

This story sounds so over-the-top that I want to believe it's made up:

Sonia Mongol says her son was not allowed to go to the restroom at his South Los Angeles school and instead had to wear two plastic garbage bags and sit in his urine-soaked clothing, according to CNN affiliate KCAL.

Mongol talked about the alleged incident in November during a news conference at Manhattan Place Elementary School Thursday. She said her 8-year-old son was not allowed to use the restroom during class. Mongol called on school officials to clarify what happened...

Mongol said after her son asked to go to the bathroom, the teacher told him that he could instead urinate in a trash can at the front of the classroom, "exposing himself in front of all the other students."

He got urine on himself and was given trash bags to cover his wet clothes, Mongol said. She also claims she was not told that he would have to spend the rest of the day wearing them.

Retired teacher Latricia Mitchell joined Mongol at the news conference and she told reporters that teachers can refuse to let students leave to go to the restroom under certain circumstances. But there is common sense and good judgment.

"After they ask you twice, you should realize something is going on," Mitchell said.

Mongol said teachers have denied her son permission to use the restroom since the incident, KCAL reported, and that since the principal did not adequately respond to the claims, she will be taking the issue to the school board.

If this happened as described, and if the teacher in question is a union member, I wonder how vigorously that union will respond, protect the teacher, and justify the teacher's actions.
