I am not sure that you have anything to worry about. Nearly every Theological school has some kind of Jewish studies program and no one is threatening them, at least to my knowledge. Also, there are many colleges that give this curriculum every semester and there is no mention of threats. Why are you so paranoid about terrorists making threats at this school? Has it happened before?
Well with what recently happened near Gaza, the fact that there is a sizable Muslism population and it is Milwaukee. Antisemetism is quite strong at every university as well.
