It is hard to say who got the letter - maybe you have to be opted in get their weekly deals.
It is good they are saying something, but in fact there has been a virtual blackout of comments from carnival other than these official letters from Cahill.
They are not offering any one on one interviews for example. I think they should, personally, but I think they are just waiting for the whole affair to die down.
Had they known CNN was going to make it the "daily special" I think they might have taken a different approach, but they didn't know.
