I have no idea what real-world scenario you are imagining when you say “research shows that fewer guns means fewer gun-related deaths.” Presumably you are promoting gun control legislation. Perhaps then you should check out the most murderous cities in the world. Most of them are in South America, which has some of theworld’s strictest gun control laws. In Caracas, Venezuela, essentially every public place is loudly proclaimed with signage to be a “gun free zone” and it is the gun-murder capital of the world. Wishful thinking doth not reality make: https://en.wikipedia.org/wiki/List_of_cities_by_murder_rate
