I agree. There is a better solution to the issue of school security than just locking down the schools 24-7. Then spending more money on a separate park. I also enjoyed the school property being open to public use as a child. But that was before the plastic playground, that constantly has some di--head setting it on fire now. We even had nets on the rims of the basketball hoops then, and somebody was always using the cement court. We had great fun using the swings in a manner not allowed during teacher supervised recess. Never quite made that 360, but we loved trying.
But those days are gone, unfortunately. The schools just got tired of buying paint to cover the gang tags, and now they buy fence with razor wire on top when they build a new school. When I was practicing for the death race, I was using a school football stadium parking lot to practice. Then signs went up and the gate got locked more of the time. They got tired of the publics use for the lot at 2 am, as a 1/8 mile dragstrip, leaving plenty of budwiser cans behind every time. The grounds crew may have also complained about me, since I was zooming the lot at 45 mph on a race bike. But I don't think so. They never asked me to leave, or anything of the kind when I would stop to chat with them. But now the lot is posted closed to the public unless an event is scheduled.
This school where the leaf was plugged in was being watched, and when the guy they told to leave before came back.... If that's what actually happened that is.
I am not saying things should not be as you would like. I'm just saying in each town, you need to live with what is in that town. And if you don't like it enough, get down to city hall or the school board and get the changes made.
