I welcome the news from Steve Irwin's widow that the video of Irwin's death has been "destroyed". Even though they may be kept under lock and key, these sorts of records have a habit of cropping up years later.
For example, there were the "confidential" recordings that the late Princess of Wales made to her speech coach. And there are some tapes somewhere of Linda McCartney, which are the subject of a gagging order.
I cannot think of many things more horrible than watching Steve Irwin's fatal encounter with a stingray. So, thank goodness the video will never be seen.
