Here is a novel approach at a safe school zone. No worries about armed nut cases showing up, no break-ins, nothing to bring harm to the kids.
Notice the geometric layout. Each of these four compounds serve different purposes.
The left compound is the grade school. Notice the large play areas toward the interior, where strangers cannot get to them. All the class rooms and offices surround it.
Upper right is the high school. Includes a track, football field and a separate baseball field.
Below that is the middle school. Not quite as large but many of the same features scaled down for the not-yet- fully grown teens.
Up to the left is the administrative offices. Also quite secure, so when kids are sent to the Principal's office, they can arrive without any outside threats.
The school yards are fenced and walled. There are observation posts all around the perimeters and the fences are electrified to discourage any would-be attacker.
What??? You mean schools are not like this? Well then what is this a picture of? OH!!! Never mind... That's a view of some of the prisons in Florence Colorado. And here I thought they were building schools to protect the kids...
