Don't wish to make light of this at all, but I do wonder- how often does this happen? After all, "shots fired" is not an uncommon thing in many cities in the US. I just wonder whether we will look back in 12 months time at the "week of hell" and realise that it was actually just a week in which we found all the things that usually go on every week that we don't hear about.
I've never even heard a gunshot, and I don't know anyone who ever has.
