When I finally saw Dealey Plaza myself I was struck by how closed
in and confined it is. It felt like I could reach up and touch the top of
the Book Depository Building. Oswald would have to have been a
spastic not to be able to hit Kennedy and Connally. I knew all that
had been said about him not being alone was bunk! Also, reflected
gunshot echoes would have made so called "eyewitness reports"
worthless.Occam's Razor says that the simplest explanation is the
most probable. Oswald did it or some convoluted cast of tens or
even hundreds perpetrated and perpetuated a grand conspiracy
and coverup.
