I don't have the answers to all of your questions but I'll try to fill the gap until someone better than me can help... The call takers are within the same room but 3 stairs seperate the two halves of the room, I believe simple geography of the building is responsible however it does seem a natural distinction. I would imagine that the reason for dispatchers not also being radio ops is simply a result of such a vast workload. No other UK service handles the volume of work that the LAS does. And to finally answer Tom's original point, nothing justifies staff not being informed of high risk addresses, it is much more important than actually getting the calls off the desk and all staff should be aware of that, I hope this is one of the many CAD errors to be fixed in the new version.
