@saexpressnews: Officer Marc Laue was seething. Minutes earlier, while patrolling the hallways of Judson High School, he had confronted a 15-year-old accused of pushing an assistant principal. The teenager, Jeremiah Johnson, had cursed at the officer and walked away. The incident led to Johnson being handcuffed and Laue ramming his fists into the boy's belly, body camera footage of the encounter shows. The case underscores a concern that has been raised by parents and advocates since schools began stationing law enforcement on their campuses: that officers might clash with vulnerable students, derailing their lives.
