TIS, I can't imagine that two people, completely unaware of one another, decided to go on a shooting rampage at the same college on the same day. That would seem to defy any odds. However, I also can't understand how one person could shoot up a dorm on the campus, killing and injuring students, and then 2 hours later, simply walk into a classroom building and blow more people away. I just don't understand how either scenario is possible, but one of them sure is, unless it was two people that were working together.
