“Ban guns. All guns. Get rid of guns in homes, and on the streets, and, as much as possible, on police,” Phoebe Maltz Bovy opines in a year-old essay at newrepublic.com. “Don’t sort the population into those who might do something evil or foolish or self-destructive with a gun and those who surely will not,” . . . Ban guns! “Not just gun violence. Not just certain guns. Not just already-technically-illegal guns. All of them.” Know anyone who agrees with Ms. Bovy?
