I've added this incident to my tabulation. I assume from comments that Waffle House is not a gun-free zone, so I've recorded it that way.
I still have a couple of blanks in regard to the Google HQ shooting two weeks ago. Did she obtain her gun legally, and was Google a gun-free zone? (I assume it was gun-free, but does anyone know for certain?)
My tally now stands at
Killed in gun-free zones - 3,566
Killed in non-gun-free zones - 208
Wounded/injured in gun-free zones -8.955
Wounded/injured in non-gun-free zones - 225
The statistics clearly show that we need more gun-free zones ... oh ... wait ...
