"ok...lets try biological weapons. The method wasn't really the focus... the number are real...the math wasn't the problem..."
Sure. How do you deliver a bio weapon effectively? To acheive the theoritical fatalities?
Its a question thats been pondered for the last fifty years, with no real solution. Consider for example, the anthrax "attack". In theory, several thousand should have died by the amount "delivered" yet that didn't happen.
Like you, I'm very concerned with the next attack, which I believe is coming before the next election cycle. But I think the complications arising trying to initiate a WMD attack make that very unlikely.
You would have a sure "kill count" by flying a plane into a packed stadium during the World Series, or one of the upcoming conventions, or using a McVeigh type truck bomb.
When you look at it from a terrorist point of view, the goal is to terrorize by any means available. You can kill mass numbers of people as we have seen by using "everyday" items, be it a fully fueled airliner, or a rented Ryder truck loaded with fertilizer and diesel fuel and an egg timer.
"Keep it simple" applies to terrorism, just as it does everything else in life.
Who cares about the technicalities of today... the number of disciples of Allah needed to murder the "infidels" will not change...and when it happens ..if the Religion of Peace is allowed to continue unchecked... it will be a national devastation.
A ratio of 1:1,000,000 will not be out of the question..
If not 2004....it may be 2010...but it will happen.
