BB guns into plowshares

I found this picture of my father, center, with his older adoptive siblings at their father's in 1940. I'm pretty sure it's the only time he was ever photographed with a gun. Earlier I speculated that playing with violent toys doesn't predict how people will grow up. In my essay on opposing enlisting in the military, I noted that my father was a conscientious objector to the draft.... Then I found this picture which kind of proves my point. Though I don't actually know if these are BB guns or air rifles or what. That's Phillip on the left, my father Peter in the center, and Gretchen on the right. My father would have been visiting his father, since my grandparents divorced long before this, splitting custody of the kids.
