The principal of Norman High School said the school will not stop students who are planning to walk out of the school Monday in protest.

In a letter sent to parents Tuesday, Principal Scott Beck said Monday’s protest is not organized by the school, but administrators will allow students to exercise their First Amendment rights to participate in a peaceful demonstration.

In the letter, Beck acknowledged the protest has been sparked by the case of an alleged rape involving two students. The incident reportedly occurred off-campus two months ago.
