Well, outrage by some whom are opposed to it. From the Journal-Sentinel:

City and school officials here are scrambling to react after it came to light that a property owner wants to set up a gun shop kitty-corner to an elementary school.

But they’re not likely to prevent the shop from opening, and they may even be limited in what they can do to keep other such businesses away from schools.

Read the whole thing for all the details.

I should point out that just across the river from where I live, in Orford, N.H., sits a small gun store across the street from the elementary school and there have been virtually no incidents of any kind.
