Well...It is not that strange. One of the characteristics of Yale (I didn't go there, mind you, but have friends who did and I've seen the campus) is that it lies in a pretty urban (US code word for "black") setting. It is very much part of the city of New Haven, although much of the campus is organized into colleges (I think Oxford was used as a model).
Compared to many other ivy league schools, like Dartmouth or Princeton, it is not in some nice suburban or rural setting--it is plopped down in a post-industrial northeastern city. Students choose it because it is an excellent school, but some of the other ivies are in a nicer, safer setting. So safety is always a topic there.
Ironically, this young woman's working environment should have been very safe. Which just shows you.
