Tom Paine summed up my thoughts exactly:
I have resisted speculating about the death of Dr David Kelly. Largely because I am generally a sceptic when it comes to conspiracy theories. If I ever find myself considering one, I am usually put off by the wild-eyed company in which I find myself. So, I am still not suggesting that anyone in government ordered his murder. I have no evidence to substantiate such an accusation and, to be honest, I don't want to believe such things could happen in my country.
I am racking my brains, however, to conceive of a good alternative explanation as to why all records pertaining to Kelly's death have been sealed for 70 years. What legitimate purpose could such an order possibly serve? I really can't imagine.
If I live to see 2073, I will be in my 90s. If blogging is still allowed, I'll post an update.
