This opens you up to two problems: 1) The "Boy who cried wolf" effect, where the cops might be slower to respond to a genuine emergency if you have a history of what they believe to be frivolous calls, and 2) charges of Filing a False Police Report, or whatever your local jurisdiction calls it. The moral of this story is, if you live in a state with open carry, don't call the cops unless you have a valid reason to be suspicious besides "OMG I'm so scared of teh mean guns!!1!"
