Jacob Sullum (Reason) writes about this question, beginning with:
Senate Judiciary Committee Chairman Lindsey Graham (R–S.C.) was trying to help out Supreme Court nominee Amy Coney Barrett when he asked her whether she owns a gun during her confirmation hearing yesterday. But the premise of his question—that gun ownership might be viewed as disqualifying a judge from dealing fairly with cases involving the Second Amendment—could not be more absurd. Here is the relevant exchange:
Graham: When it comes to your personal views about this topic, do you own a gun?
Barrett: We do own a gun.
Graham: OK. All right. Do you think you could fairly decide a [Second Amendment] case even though you own a gun?
CNN highlighted that exchange in a headline and tweet, noting that “Barrett says she owns a gun, but could fairly judge a case on gun rights.” The Independent also considered the point noteworthy: “Nominee owns a gun, but says she would rule ‘fairly’ on gun control cases.” So did Fox News: “Barrett admits to owning a gun, says she can set aside beliefs to rule on 2nd Amendment fairly.”
Sullum’s analysis strikes me as quite right; a bit obvious, to be sure, but the sort of obvious that people (or at least headline writers) apparently need to be reminded about.
