Why are you focussing negative messages on Birmingham University? The same is true for most other Universities.
Even where most live in College (Oxbridge), which is pretty secure they can be attacked on the streets, and a few cases happen every year.
Are you saying the West Midlands police are not taking adequate steps to combat such crime? That would be of interest.
BTW when I lived in the US, my Campus had emergency aid buttons about every 50 yards across Campus. You pressed one and the Campus police would rush to that spot. It had seriously high crime, was in a dangerous area (or close to one anyway). But on the whole I felt pretty safe.
My local University in a very safe/leafy place has had rapes and at least two suspicious deaths so far this academic year. It is also far less buzzy than Birmingham University was, when I was there. however I have felt no need to come on here to terrify parents of students in my town.
