Could you provide a url for the stats you are referencing?
U.S. Department of Justice study http://www.ncjrs.org/pdffiles/165476.pdf estimates 1.5 million defensive uses annually. Numbers seem to vary from 0.8M to 3.0M depending on how you squint at things. Consensus is that the numbers are large, most of the time just displaying the thing is enough to stop the attack, and you have to actually have one to be able to display it.
