I never heard any stories from the media reports that said it was ANOTHER gun free zone shooting.
There are more non gun-free zone shootings than there are gun-free zone shootings, so I am not sure why you are complaining about the media.
In fact, it would appear that most mass shootings don't happen at malls, work, etc., but happen in the most dangerous place in the world for most folks, home/neighborhood. Such domestic mass shooting often do not make the national media either. They don't have the draw or excitement of something like a shooting at a mall even when nobody gets hurt there.
The media doesn't care if it is a gun-free zone or not. They are just looking for what will grab attention and sell ad space.
