The "Wayback Machine doesn't have that page archived". As reported in #71, Google didn't spider the page for the first time until 12/14/2012 at 6:58pm, about nine hours after the shootings, and they admit the date they assigned to the page is wrong.

Google doesn’t ‘assign’ dates to pages. The dates come from the system clocks of the servers on which they reside.
