The current estimated number of firearms in civilian hands is around 466,000,000. If your target is to complete confiscation within 5 years, that would mean 93,200,200 confiscations per year. Let's say (arguably) there were an average of 5 firearms at each "location". That would give us 18,640,000 confiscation actions. If you assume an "average" confiscation (i.e. who has the firearm(s), where do they live, plan the action, how does it take to "find" the firearm(s), collect and process them) requires 3 days, then we are looking (assuming there was only one team) at 1,864,000,000 days to complete confiscation. Too long? OK. Lets say we needed to complete the entire task in one year. We would then need approx. 5,106,950 collection teams. Easy peasy. Right?
