Shaheen contended that Kelley’s conviction should have warranted a dishonorable discharge given his extremely violent crimes of assaulting his spouse and child — Winslow agreed, but said it was up to the Judge Advocate Generals Corps to decide what type of discharge a military member should receive.

Winslow was right about getting in trouble with other members of the committee. Before Winslow was able to conclude his train of thought, a clearly irked Sen. John McCain interjected to say that commenting on the legality of assault weapons “wasn’t in [his] area of responsibility or expertise.”

As Vox pointed out, Winslow’s opinion likely stems from his medical background. Given the number of Americans who have died because a civilian was able to purchase an assault-style weapon, it’s certainly not an overstatement to say that their legality is “insane.” Gun control is a public health issue. Winslow’s opinion, albeit put in slightly different terms, is shared by the American College of Physicians.
