Well, firstly, Heavymetal, the BBC is not in the business of making money at all, it is not a private company, and you cannot compare it on those grounds with CNN, ANC, CBS or any other US broadcaster. In itself, that doesn't negate your argument of course.
Secondly, your argument that:
"If the first targeted terrorist bioweapons attack on the US was meant to cause widespread death, it was an unmitigated failure. The medicines worked better than anyone imagined, the authorities actually functioned competently(for the most part) and the dispersion pattern of what I read experts were amazed was probably the highest quality weaponized anthrax possible just didn't operate as predicted."
is true if indeed that was the case, and let's be honest no-one really knows. But the anthrax episode and any smallpox attack are very, very different scenarios.
Thirdly, the reason why smallpox would cause widespread death is because it is easily transmissable and practically no-one has immunity to it, because it was eradicated around the world as a disease. Therefore vaccines are at a premium. Now, both the British and American governments have recently been stockpiling it, which would limit the deaths in those countries, but it certainly wouldn't around the world, there is nothing like enough of it. Nor would the presence of vaccines prevent many from dying even in the US and UK.
As for the credibility of the British media being suspect, I'm not sure how you can argue that any more with Britain than anywhere else. The problem with smallpox being used as a weapon is one which the west is more than aware of, and this particular programme wasn't portrayed as news item anyway, it was a drama.
