About a year ago, I took a couple of hours and systematically looked at articles about Mormon missionaries in the American news media.
With only a couple of exceptions, they were extraordinarily positive. What I noticed is that missionary stories needed to be more than just typical Mormon missionary, but the missionary with an unusual challenge or the missionary with the unusual story.
This fits this. As always, letting our people speak -- when the news media allows it -- is the best P.R. the church has.
