I'd add that "armed" doesn't mean necessarily a firearm. I don't know what threshold is used in after-action reports (written by those involved or others), but presumably finding a pocket knife on someone counts as "armed". Would personal protection devices (mace, batons etc) count as armed. Call me a cynic, but 104 people being 'unarmed' makes me think the reports in those cases simply lack creativity in defining "arms" and, (again cynically) I expect some number of the other cases the individuals were either helpfully discovered to be armed after the fact. (And in some cases actually provided with arms after the fact.)
