Jesus Family tomb story?

There's much talk of James Cameron's new film about a tomb (discovered in the 1980s pleas note) which he and so called academics allege to be the tomb of Jesus and his family. It doesn't take great scholarship to see some obvious flaws (e.g. the assertion that a tomb of Jesus son of Joseph and Mary could be one of MANY people with such names. -Much like today finding a gravestone of John son of David really not a rarity) but fortunately Ben Witherington has done even better and put together a very scholarly response.
