@Happytimes2001 can you just share your source? Or are you generally looking at Chicago? I can tell you my son has been there for two years and knows of no issues of violent crime.
Here is the first article in google that I found listing the 20th most dangerous campuses in the US.
https://insurify.com/insights/ivory-tower-incidents-americas-most-dangerous-universities/
The 20th on the list had 11.1 violent crimes per 1,000 students.
The University of Chicago had 8.57 violent crimes per 1,000 students.
Other schools not on the list:
Harvard 8.39
Yale 13.80
Stanford 12.09
MiT 14.08
I don’t know why YSM aren’t on the above linked list, but out of the HYSMC group, Chicago is in a very close 2nd place on the list of safest campuses.
