Then the question is does the 1000 member security force for Tufts include all the campuses? JHU campuses are both in the city of Baltimore, and not that far apart, but the Homewood campus is in a lovely residential area with neighboring old homes and churches, parks, and other universities (Loyola, Notre Dame) and private schools. The hospital is in an area that requires barbed wire around parking lots and security to get to your car.
The two schools don’t have the the same set ups or needs. I assume each school has what they need to keep their students and faculty safe while working with the local police force. USC also has a large security force that extends off campus to protect students. I worked in the courts in Boulder for a year and found the campus police force better than the city police in securing a crime scene.
