In this brief encounter, Dawkins mentions the Book of Mormon and highlights the fact that it was written in the style of "16th Century English" despite being written in the 19th Century. He reasons that, on this basis, the work is a forgery and Joseph Smith is a "charlatan".
Brandon Flowers, frontman to the Killers (whose music I love) is a Mormon and gets quite agitated by this, at one point telling Dawkins to "do your research" in a terse exchange.
Despite this awkward moment, it was nice to see that the pair were able to part amicably with a handshake.
