They rely on appearance and goodwill. No one will send their kids to a school, where homeless people kill each other on campus (which is what this appears to be, but More Will Be Revealed).
I won't speculate, but it seems as if they had simply kept giving jobs to that contractor, it would have remained silent.
I'm surprised no one removed the body, in all that time, though.
But the mentally ill homeless veterans wandering around their kids' campus a couple decades down the road - that's scary, in an immediate, visceral way, for anyone.
It was appearances and public image, 100%.
(Not all... etc)
I know it's not okay to speak in absolutes, but this might as well be a law.
Colleges and Universities care more about public image than about needless spending, efficiency, and waste.
Their entire existence hinges on their image, especially for elite schools.
