"It is so fucking obvious that other shots were fired at Kennedy
...
All you have to do is read into it some"

Those two statements define exactly what the problems are with these issues.

It is NOT fucking obvious, otherwise there would be universal agreement. THAT is what causes people to consider other options.

The fact that you can "read into it" opens up elements of doubt AND interjects the author and readers preconceived notions.   It is hard to find anyone with a truly open mind. The "consipiricists" seem to latch onto whatever is supporting their wish to have an alternate reason, and that clouds their ability to really consider all views.   The "anti-conspiracists" work exactly the opposite. They consider the source and look for ways to knock it down.

JEEZUS!!!
