Preface: I agree with you. I'd be really curious to see an "aging report" for firearms that are used/involved in mass-shooting incidents -- I roughly know the answer for the most recent and most newsworthy (read: horrific) incidents. I'd just like to see more data on the topic, specifically 'time from manufacture to use as a murder weapon', to better understand exactly how much potential impact there is. I'm aware private sales exist, and the implication that mentally ill people may turn to private sales, but I'd be curious to see the data on this nonetheless. I'd similarly be curious to see a breakdown/data on "source" of weapons used in incidents like this (and even on attempted/homicides, domestic cases, etc), as well as an aging report -- to better understand how much "impact potential" legislation actually has. While I do support legislation, I'd also like to better understand how impactful it could be and how quickly we might see an impact; I'm also aware of semi-mixed efficacy from (some) prior legislation (state & federal), though I'm personally still in favor of additional legislation, even if only because my 'gut' says it would be a net positive impact.
