Above is another story with video taken inside. To me it is odd that the chairs are pushed in, stacks of papers on the tables. Other photos (I can’t find now) show stacks of bins and stuff pushed up against the walls and up above the windows in the classrooms. It looked more like rooms used for storage rather than a usable classroom.
(And in the above video - what is up with all of the fans stored in the classroom? In December?)
The whole thing just seems really odd. Especially compared to images from other deadly attacks.
