When telling stories involving people motivated by faith, it is crucial for readers to be able to hear the voices of these individuals describing their beliefs and motivations. But what happens when it is either impossible to interview the key people, perhaps for legal reasons, or they have no intention of answering questions from journalists or anyone else?

This is where the Internet and, especially, forums linked to social media have become so important in this day and age. You can see how this works in a recent New York Times story, which centers on the latest shocking tale of young people from the American heartland who have been arrested while trying to flee the evils of America to join the Islamic state.

The story, this time, unfolds in Starkville, Miss., a university town in which the locals, as the Times team states in classic elite mode, "tend to be proud of Starkville’s relative tolerance." The key players are Muhammad Dakhlalla, a young man from an outgoing, community oriented Muslim family known as "a walking advertisement for Islam as a religion of tolerance and peace." His fiancé, 19-year-old Jaelyn Young, is an honor student, a cheerleader and a  recent convert to Islam. The two tried to marry as Muslims, but her father refused to grant his permission. Their plan was to say they were flying to Turkey on their honeymoon.

Obviously, legal authorities have been following their activities via email and social media. That leads to this brief, but revealing, exchange:

Ms. Young, who three years ago was broadcasting silly jokes on Twitter and singing the praises of the R&B singer Miguel, had more recently professed a desire to join the Islamic State, according to an F.B.I. agent’s affidavit in support of a criminal complaint. On July 17, the day after a young Muslim man in Chattanooga, Tenn., fatally shot five United States servicemen, Ms. Young rejoiced, the affidavit alleges, in an online message to an F.B.I. agent posing as a supporter of the Islamic State.

“Alhamdulillah,” she wrote, using the Arabic word of praise to God, “the numbers of supporters are growing.”
