I'm surprised you didn't get any response at the mall. I know the Scott county(Davenport is in Scott county) Sheriff is not a fan of OC. Also, the mall has a no weapons policy but you would only know that if you were seriously looking for it as its only posted at the food court entrance and the other main entrance near the recruiters office. Which Casey's did you stop at(there are five in Davenport)? Generally all of the FUD reactions are in the smaller towns here in Iowa, and also the two liberally centered cities such as Des Moines and Iowa City.
