^All this is about psychological deterrent really, which is useless for people crazy enough to actually do anything. They're just weeding out the gun-toting momma's who carry concealed in their purses.
Not that SDC has a lot of choice in the matter, other than loosening their CC policy which I'm not necessarily suggesting they do. Some of this is driven by Missouri legislation, and some of it has to do with covering their asses in case something crazy ever happens. It's just annoying that none of it really matters unless you go full airport style security which is basically impossible.
But to respond to the original comment, yeah it does look decent. They've done a good job on keeping up the overall aesthetic on the new buildings for the past several years. The Culinary School was the only one that's slightly out there.
