I was horrified to hear of this terrible event, and I’m sorry you feel like BC doesn’t care. Though I know it might not ameliorate the lack of a public statement, my library assistants have heard nothing but care and concern from BC staff, students, and faculty. As to the population: a recent Pew survey estimated that nationally, recent college graduates were about 3% Jewish, and Boston College Hillel estimates BC’s Jewish population at 2%. I doubt that’s enough of a difference to influence concern about antisemitism. I’m sure BC as a whole cares; perhaps student groups could help encourage BC to turn that care into a public gesture of some kind.
