Has your child ever called you in tears after something happened? If so, then you probably know just how emotional and irrational a parent can get over their child’s distress. No one knows that better now than 27-year-old Christopher Freeman.

Freeman reportedly received a FaceTime video call from his son at around 3 P.M. His son was at school at the time, and he told his dad about how a teacher had “slammed” him during an incident at the school.

His son’s state and the story immediately drove Freeman into an irate state. He promptly called up to the school and spoke with the Assistant Principal. The Principal later told police that Freeman threatened, “If this isn’t my son, you’re all dead.” According to the police report, Freeman decided to grab a loaded Romarm/Cugir AK-47 weapon and head up to the school to confront the teacher.

Freeman arrived at the school and tucked the gun into the front area of his pants. The firearm was clearly visible to a school resource officer as he stomped into the main office. The resource officer trailed him as Freeman burst into the office and shouted, “I want to see the guy who slammed my son. I’ve got something for him.”

While Freeman’s frustration is understandable, the threatening situation prompted the officer to put the school on a Code Red lockdown. Police arrived, and Freeman was ultimately arrested. He’s facing charges including possession of a firearm on school grounds, disruption of a school function and aggravated assault.

According to Freeman, he didn’t realize he had his weapon because he carries it all the time for protection. He also told officers that he never intended to harm anyone.
