The desire for balance

I have been perusing a number of JFK conspiracy sights as of late and I have been questioning what makes the story so interesting to so many people. I have seen so many just absolutely ridiculous websites that talk about every little detail of the shooting and Oswald, but after a while the facts do tend to add up. You can tell that Oswald had shot both JFK and governor Connally are both shot by Oswald by the same bullet. I heard somewhere that there were around 3000 pieces of evidence to back up this conclusion. So why is it that so many Americans refused to believe what was told, why was the commission being confronted with trying to cover up something when you can tell pretty easily what happened. Its been over 40 years and people are still trying to prove the conspiracy, yet still no solid evidence have been found. I think that people who are so into the JFK assassination want to think that the world just isn't so chaotic. The president couldn't just be killed by some guy with a gun like this, there had to be a set up there had to be some logic behind that. If these people can find some conspiracy it would comfort them in a strange way by knowing there was something besides this and by the same bullet. I feel that a lot of the conspiracy theories are made by people who want to think that there was something big at stake. They do want to think that some nobody can kill someone as big as Kennedy. I heard a great explanation somewhere,  I can''t remember the source but it stuck with me. It said  that if you put 6 million murdered Jews on one side of a scale and the Nazi regime on the other side they would balance out the biggest crime next to the biggest criminals. However, if you put the murdered president on the scale across from some low life like Oswald, the scales would be extremely unbalanced. People want balance and putting a conspiracy theory next to Oswald balances everything out real nice.
