the error bar says

psychologist professor Drew Westen reports in The Washington Post that people aged 16-24 commit half of all murders in the USA, mostly gun-related. this, he argues, is because young people are more vulnerable to mental illness, & their frontal lobes are under-developed

does frontal lobe development stop gun crime?

the article contains a lot of claims & links to a wide variety of sources. some claims are not supported, some links don't work & some of the data are quite old. but, in general, it looks correct, at least, to say that most murderers are young men

but since most of the victims of murder are also young, older non-murderers may have no more developed frontal lobes than younger murderers. instead, they may just have survived this most dangerous period of life

no sources are provided for the frontal lobe development claim, nor for the recommendations of neuroscience on the minimum age for gun ownership. no alternative explanations are considered
