He’s been talking about that for a while. It has been on the internet (try and google “the perfect day” scenario—it’s similar to what happened in Breslan in Russia). I heard him say last week that his tv program on headline news will discuss it in more detail the first couple of days this week.
Story from about 2 weeks ago.

I googled “the perfect day” and all I got was a whole bunch of wedding stuff - any more specific?
