I read an article one time when someone questioned her accuracy about the assassination. Her pat answer was supposed to be all the same: Who was in that car, you or me?
I remember a show on The History Channel, about the limo and what happened that day. (I was in 12, and in HS algebra class at Prospect HS, Mt Prospect, IL) Mrs C seemed somewhat defensive in her answers to the interviewer's questions, IIRC.
