It was a smart move for that public speaker to bring this up since the case hit the national news and is being talked about all over the place! Much of the public know about it and any JW who is interested in the news would have heard about it.
It would have looked odd if it were not mentioned. This way the religion can put their own spin on it. Ignoring it would have raised further questions in the minds of already troubled JWs who have enough doubts about the religion.
