I played excerpts from Hillary’s speech from today, in which she references “hurling” her “bookbag” across her room at college on hearing of the assassination of MLK, as well as wearing a black arm band in a protest march in Boston in the aftermath of the murder.
Listeners are e-mailing skepticism about their being bookbags and arm bands in 1968. I have no opinion, being 12 at the time. E-mail evidence to firstname.lastname@example.org.
UPDATE: Bookbag history here.
