Many if not most Walmarts in my area have these. I believe that stores are installing them when the amount of incidents they have with crazy/wild folks is large, as I've seen police at the stores with them rather frequently. This sadly seems somewhat corelated with nearby socioeconomics, but it doesn't change the fact that the things the police are getting called for are real. Like another poster I tend to try and park near one if I have to shop at a place with one.
