I don't think that everyone haveing guns would have helped anyone in this situation. Just the crossfire alone would have killed people. I do think that schools should provide some kind of training for their staff and students about what to do when something like this happens.
According to the news media all the gunman used was 2 pistols. To kill 33 people he had to have reloaded at least once. I have taken a set of courses that deal with this exact situation and how to survive it. Here is a link to the website:

I would highly recomend these courses to everyone. There isn't any other instructor out there dealing with these modern issues in such a comprehensive way.
A little prevention would have saved a lot of lives.
