careful chaps......don't forget this is now sub judice and not really up for public discussion until the trial ends.
On a more generic note though......what is the current "accepted safe practice" for walking on tiled roofs? Scaffold? Crawling boards?
I still have memories from falling through the asbestos roof of a large pigsty when I was aged 12......the bloody pigs rushed straight at me looking hungry. I jumped straight back up through that hole in the roof, god only knows how. Cut my shin to the bone - I still have scars on it now. I think I was lucky that day
