Kids in the high school where I taught for 20-somwthing years learned to wedge textbooks, or even pebbles into the door jambs to keep the panic bars from locking the doors to outside entry. City fire codes prevented disabling fire exits, and the school had over 100 fire doors. Kids would disable the automatic locks to let their drug pushers roam the halls disguised as students. Try controlling 3000+ high school brats sometime!
It was only 1500 in my case and we only had about 20 doors to watch.
