I'm not arguing that anything directly proves anything, I was arguing the opposite: that increased legal firearm ownership, including legal ownership of bump stocks, high capacity magazines and what have you, seems to have had nothing to do with overall homicide rate of the country, nor the firearm-related homicide rate of the country. The number of "mass shootings" has increased in recent years though (despite still being an incredibly statistically small cause of death, even when compared to other "preventable" causes of death like drunk driving)… so maybe this indicates that it's not the firearms themselves that are the problem, but other factors not being accounted for in mass media analyses of these events, for one reason or another. For example, SSRIs will never be blamed for anything on television news, as long as pharmaceutical companies advertising on their stations are a core part of their business.
