When you were at Camden, did you ever have a problem with crime, or know anyone who did?
Back in the mid 1990's I toured RU Camden law school. It was around sunset, and I asked the postal carrier if the area was safe--his reply was "get out of here before dark."
We also visited Cal about 6 years ago. The area around Berkeley had a similar vibe/element to the New Brunswick area. I think I read somewhere recently that there has been a crime issue near/on that campus. I knew several students at Seton Hall Law who had their cars vandalized, broken into or stolen. It's life on a campus in an urban area. Be aware of your surroundings.
We had evening classes ending as late as 10:30. I never heard of anyone having a problem, but keep in mind that the students were leaving as a group. There is a shuttle to the parking lots. Some students took the high-speed line from the station two blocks away -- I never heard of a problem. This might be because the area was patrolled by the Rutgers police, the county police (who function as the Camden police), the Port Authority police (because the campus is adjacent to the Ben Franklin Bridge) and the Camden community college police). My impression was that the campus police were extremely willing to challenge anyone who came on campus who they thought might not have a good reason for being there.
There is a huge exception: some years ago there was a rapist preying on women near the campus. As I remarked on another thread, this individual made the mistake of walking into a Vietnamese-owned grocery, grabbing the proprietor's wife and threatening bodily harm. The proprietor pulled out a gun from under the cash register and shot the guy dead to the regret of no one.
There have been crimes against students living in the dorms. These are occasionally street crimes, but they are at least as often crimes that occur when students visit liquor stores or the nearby bar.
I should also mention that it is impossible to enter the law school without a card swipe or without dealing with a security guard. But I do not know if this is true of all campus buildings -- obviously, it should be.
I don't think there's any greater crime problem at Camden than at the other campuses - by a fluke of geography, the campus is pretty well isolated from the bad neighborhoods in the city.
I haven't been on the Cal campus for a long time. In my experience, one has to be careful there, but no more than in any other urban environmenta.
