I don't know what "precludes" means but I do know that state cc license doesn't matter because it is a private campus. Technically if I bought a handgun and took it directly to the campus and never took the gun off campus I wouldn't even need a cc license. What I'm saying is on private property the state can't enforce carry laws. Only exception is a river boat and airport. You can carry on a public campus if you're picking up or dropping off a student and nothing else.
There's actually nothing illegal about carrying on any university campus in Indiana. State laws against carrying are specifically for schools (High School and younger), not universities. There's a thread discussing that somewhere around here.
