Some schools still have common sense.

Here are the deets from The Post:

Woodbridge High School handed three-day suspensions to 303 students who walked out of class last Friday to 'express their views' and protest federal immigration enforcement, principal Dr. Heather Abney told parents in a letter obtained by 7 News.

The demonstration, which was not backed by Prince William County Public Schools, eventually spilled off school grounds and onto the streets, forcing local police to manage traffic and oversee the hundreds of rebel students involved.

The school didn't authorize anyone to leave, but 303 left, so they're all suspended.

Simple as.

However, it appears that no one learned their lesson, as another student-led walkout is planned for Friday as well.
