From a short blog post on the Corner:

First reports are notoriously wrong.  The shooter already has been killed then resurrected by the media.  Some media are in a frenzy and so the reports are particularly untrustworthy at this time.  Now is not a time to psychoanalyze the attacker by using a media-supplied telescope that already said he was dead, and that there were multiple attackers.  Media: STOP, please.  There will be time to pursue answers and justice after Christmas.  We must remember that family members lost loved ones just before the holidays.  Justice and answers will come with time.

Absolutely right.
