Mutual respect for the public space is key. This is what I mean when I think about high trust environment. Basic example: that computer room full of nice iMacs. How many cases of theft or vandalism would it take for the school to shut it down? At first, it would be forced to surveil and severely limit its access (higher upkeep cost). But if the students kept stealing or smashing the equipment, eventually the computer room would be no more. And good luck having a wood/autoshop in some areas: that's begging for a lawsuit after someone ends up misusing the tools or straight dead. Now expand this reasoning to everything you see on this video. It's no wonder schools in bad neighborhoods end up costing more than schools like CHS.
