James my brother put me onto this. he asked, had i seen the footage on the bbc website of people falling over on an icy pavement (50 seconds into the video). it seems that the film crew found themselves a spot where people were falling over and staked it out. presumably they saw one person falling over and then decided to see if more would follow. not that they would have gone out with a watering can the night before, no, but it does seem a bit heartless.
i'm all for a bit of entertainment, but i would you have felt a tad uncomfortable about filming the old folk knowing they were about to come a cropper? the daily mail also found an icy spot to run a disaster watch.
