Uvalde + Buffalo + Parkland = Make guns 21+.

Uvalde, Buffalo, Parkland – the common thread in these massacres? All were committed by under-21 boys who purchased their guns legally. In mass shootings, 77% of the murderers obtained their weapons legally! Over 17% of all homicides are committed by those 18-20, and most weapons used in crime are obtained legally or through straw-man purchases from legal sellers [1].

So you’re telling me we could reduce school shootings and potentially stop 4000 deaths per year, just by making kids wait until they are drinking age to buy a gun [1]? It’s not quite that simple – with America awash in guns, eliminating access wouldn’t stop perpetrators entirely. But it’s worth noting that the aforementioned trio of shooters didn’t have criminal records, and didn’t have criminal contacts on whom to rely for illicit weapons. If only 1 in 4 young adults were stopped from obtaining a firearm, this would reduce deaths by over a thousand per year. From a gun-rights perspective, no right has been taken away – just shifted a few years to enable young minds to develop and gain impulse control (brain development actually ends at 25).

Most reasonable gun safety measures are supported by the majority of Americans, but this particular improvement was also enacted by a conservative state – Florida ended gun sales to the under-21 crowd after the Parkland shooting. If Florida can do it, then virtually every state politically to the left of FL should be able to make this change. Narrow Federal legislation in this regard might be possible (though unlikely) in the current moment [2]. As this latest tragedy focuses our attention on the issue, I hope politicians will focus on simple, attainable changes like these.

[1] The FBI data uses slightly different age ranges, but if we add 1/5th of the homicides committed by those 20-24 to homicides committed by older teenagers, we get 1910 homicides in 2019 – this is 17% of all homicides that year (where age of offender is known). When scaled to 2021 homicide levels (using 6.9 per 100k rate and Census 2021 population), this is 3893 homicides per year – 79% of which are estimated to be committed by firearms. That’s 3110 homicides per year. Using CDC data we find another 900 suicides by firearm within the 18-20 age group – for a total of 4000 deaths per year!

[2] Theoretically this should be easy to pass at the federal level, but Congress has become so ossified and reactionary that nothing will pass there.The guns-at-all-costs crowd has grown more extreme, with many calling for ALL weapons to be legal (yep that includes nuclear weapons, according to a former TX state representative).
