And now it's everyone's job to point fingers and talk about what THEY would have done. What makes people think that if all the people on that campus didn't do anything differently, that THEY would have? Were the victims "stupid" for not doing something differently? Were the cops and security guards really all that much more incapable than cops and security guards the rest of the world over? Should there have been metal detectors and fingerprint ID's and guns banned and video games outlawed? Would that have stopped this? You know how much of a pain in the ass that would be for the millions of other people around the world that have to walk around in society every other day but that one, in every other place but that campus? You think you can stop something like this from happening? The more intent you are on stopping this stuff, the more intent people are to showing that it can't be!
