A senior prank is causing a major controversy at a Phoenix high school. Some students at North Pointe Prep posted a video online of seniors running up and down the halls of the school wearing masks, shooting squirt guns and terrorizing underclassmen.
The video is based on the horror flick "The Purge", and now some parents want the school official who gave the students the OK to resign.
The school is backing the students, saying rules were set in place so no one would get hurt. The parents say the video went too far.
