Rates of violent crime have been declining heavily all over the developed world, regardless of the number of guns. Also, while the number of guns has gone up, the level of gun ownership has been going down. Gun sales have risen due to paranoid buyers getting multiple guns.
If violent crime has been declining the developing world, regardless of the availability and prevalence of firearms......
Furthermore, the US has the highest firearm ownership per capita, but we are not near the top of violent crime or homicide statistics. There is no correlation, unless "scientists" intentionally omit all data that contradicts their assertions and hypotheses.
Gun control is an existential debate. The people who attempt to reclassify their personal ethics and existential motivators as "science" are fit for a mental institution. Ironically, adjudicating these people as mentally-ill would also prohibit them from owning firearms (in theory).
