Black 4th Grader Expelled After Reporting Racial Slur at Catholic School

A Black student at Madeleine Catholic School in Portland was reportedly expelled after his parents complained that he was called the N-word. Instead of supporting the child, the principal called the police on the parents during their meeting.
The principal has since been placed on leave, and the family has hired legal representation. Thousands have signed a petition demanding justice.
What are your thoughts on how this was handled?
