I only wish to express my sorrow to the families who lost loved ones today.
Please, everyone, I know that you angry for what has happened, as am I. But anger and fingerpointing is is the very thing that made this act happen today. I KNOW those responsible will be brought to justice, whether it be this life or the next. Just please, don't let this incident put us into a frenzy of anger and cause us to destroy ourselves. What has happened has happened, no matter who's fault it is. We need to now look forward and figure out how to prevent it from happening again.
Just my two cents, for what it's worth.
