This is true, but if you read the linked story, it’s talking about neighborhood improvement at JHU’s East Baltimore campus (the medical campus). It’s not talking about the Homewood campus, where nearly all JHU undergraduates are located (except for the Peabody music students, who are at yet another campus).
The East Baltimore campus is not in a good area, as noted in post #3 above. However, Homewood is literally miles from the East Baltimore campus, and is adjacent to much better neighborhoods. Admittedly it would be easy to get confused, because the JHU stock photos that were used for the story show the Homewood campus, rather than the East Baltimore campus.
