So I've asked a question about powered armor specifically as a solution here, and largely rejected that solution, but I can’t shake the feeling that I want a setting without guns. What is the best way to get rid of them for something like a somewhat less violent cyberpunk setting using plausible near-future technology?
The obvious solution is probably just political factors that lead to a reduction in the number of guns, but without technology to support whatever group is taking away guns, it is all but an impossible problem logistically. So, what is a good approach?
Infomocracy by Malka Older gives one solution, in which a device that makes guns virtually impossible to use is developed. It's called a Lumper, and uses targeted magnetic fields to make it impossible for guns to fire given the precise mechanical action required for each shot. I really don't see how it could actually work, and would prefer something more plausible, but it is an interesting sort of handwave.
