I love that phrase "a throwdown", as if the CIA have been training their operatives for years in honing their "throwdown" skills. Terms like that seem to lend more authority and credibility to what is simply being claimed as the planting of evidence.
The problem is people are tired of continually refuting these daft conspiracies. They don't bother anymore, so the theories are left to fester away on their own. Occasionally though, you get a glimpse of the conspiracy mindset, in the mainstream media.
Most recently, was Mohammed Al Fayed. Ruth Dudley Edwards wrote a good piece for the Telegraph which was syndicated in last Sundays Indo. Fayed has always sounded like a whinger and complainer extra-ordinaire. His failure to be accepted by the British establishment, has left a legacy of bitterness, which made it easy for him to slip into this mode of thinking. He is basically blaming the same establishment for the deaths of his son Dodi, and Diana. But the implication of what he is saying, is that the British intelligence services are being directed not by the British parliament, and government, but by Prince Philip and his son Charles! It led to bizarre scenes at the inquest, when both Fayed's lawyer, and the former head of MI6 were put in the embarrassing position of having to make and answer this specific allegation!
The whole conspiracy mindset in my opinion, seems to stem from a childish need for simple answers, and at the same time, a naivety about how the world actually works. Fayed has his own problems as well, including obviously an understandable level of grief for his dead son.
