I get what you are doing here but I think you are misled. The police has a monopoly on violence to protect the state apparatus and the ruling class. Protecting normal citizens is a means to an end of that, it never was the goal. The US police originated in a force that brought back run away slaves. Are we talking about run away slaves? Is there private property at risk? Is the school shooter threatened any organ of the state? So why bother? TLDR ACAB
The why is beyond me. Trying to meet state hours in minimal days to save operating cost? Lunch pulls admin and other staff to monitor instead of doing their other routines, so they try to minimize it maybe?
15 to eat, kick them out to recess so they can clean tables for the next group.
Many don't bother to eat because the lunch line eats up their time, too.
Where I am, parents have to pay extra to have their kids stay at school during lunch. Like we're paying a babysitter to watch them during that time. And then if we don't pay the kid isn't even allowed to stay on school grounds at lunch time.
In my country lunch is completely different. We also only have 15 minutes to eat, but we just eat in the classroom with the teacher of the previous hour. So you have to bring your own lunch, in my school you can even buy any food. But at least I am allowed to go into the city during lunch.
Shit schools make poverty trapped children, and poverty tapped children are more willing to not care about the legality of trying to survive or gain reputation with their friends/city. And the police love locking away people.
It's a win/win. You lower the cash to schools, increase the cash to police, police catch more "Criminals", and the politicians who sold this can tout the tough on crime to the next election cycle.
Until the criminals learn to bribe police more than what politicians give them, and start buying more and more cops, and puff you are in a dictatorship ran by thugs
Back in my old time, cafeteria food was also shit, so everybody was bringing their lunch (a sandwich, some fruits, a little boxed juice) and we called a day.
Is that piece of bread and rice (rice right?) and the piece of brown chicken we are seeing in the corner (badly cut out of the picture for more dramatic effect) free of charge? If so, what are you complaining about? If not, why don't you bring your god damn sandwich like it has always been?
