Why? How?

Six people died at Northern Illinois University today.

We know that the gunman was a former student. We know that he entered a classroom and fired several rounds from two guns. We know that the gunamn killed five undergraduates - four women and a man. We know the gunman killed himself. We know that Northern's security system worked properly - lessons from recent threats and tragedies that Northern administrators took to heart.

As a Northern Illinois fan - my brother graduated from NIU, still lives in DeKalb and hosts the best tailgates around - questions are flooding my mind.

How did the gunman obtained enough ammunition to injure 17 people and kill six? Did he act like someone who might shoot up a classroom before he did so? Did anyone say anything? Did anyone try to help? Could anyone?

Were the guns were his? Were the guns were purchased legally? Should just anyone be allowed to buy guns and ammunition? Are the rules we have in place enough? Are they too much?

I often hear, "Don't read those stories!" from friends when I mention that I read the horrifying news stories about child abuse. Those stories give me the same shivers and evoke the same sighs as the tragedy at Northern Illinois. Why? How?

Did anyone see anything? Did anyone say anything? Did someone see it coming? What happened?

What now?

We don't know anything yet.

We only have questions.
