The New York Times reports that Shirley Sotloff, whose son Steven Joel Sotloff is a freelance journalist being held by ISIS, says in a video message to her son's captors:
“As a mother, I ask your justice to be merciful and not punish my son for matters he has no control over,” Ms. Sotloff, a teacher from Miami, says in the video. She explains that she has been studying Islam since his capture, and then urges ISIS’ leader to follow the path of his religion’s founder: “I ask you to use your authority to spare his life and to follow the example set by the Prophet Muhammad, who protected People of the Book” — a reference to Christians and Jews.
She adds that in her study she has learned that Islam teaches that “no individual should be held responsible for the sins of others.”
“Steven has no control over the actions of the U.S. government,” she continues. “He is an innocent journalist.”
Note that the story does add that "People of the Book" is ”a reference to Christians and Jews." This is good. In some other media reports online, "Book" has a lower-case "b." What, precisely, is this "Book"?
However, look for mention of Steven Sotloff's specific religion in the Times article -- or in coverage of Shirley Sotloff's video in the Miami Herald, the UK Mirror and other mainstream news outlets -- and you won't find it.
