We had a popular shooting team and both the student and teacher parking lots were filled with trucks with rifle racks filled with rifles and shot guns.
Most people carried pocket knives and competed to see who could get the coolest one
Never had a problem
During hunting season shot guns were visibly on racks in the back of pickup trucks in our high school parking lot. No one thought a thing about it. Knives were visible on persons within the school as well. No incidences. What does that tell you about how far our nation has gone a rat hole?
