Sadly and grimly, one of the first things I thought when I saw news of the recent massacre, was "it's been awhile."

And the OP's link bears that out. Of the 15 previous to this one, 7 of them were in 2012, with 76 killed. This is the first of 2013, with 12 killed.

2012 was a shooting gallery, with one ghastly atrocity leading up to another, until the mind numbing tragedy of Sandy Hook.

2013 has been relatively calm.

Maybe even the maniacs were temporarily shocked into submission after Sandy Hook?

May all those lost rest in peace.
