1) We all know that eyewitnesses see incredible things. The "eyewitnesses" at Dealey Plaza all heard shots from IN FRONT and on the ridge, when acoustic evidence unquesitonably puts it behind.<<<<<<<<<<
One thing, there is a difference between the visual sense and the audio.
Visually you can pick the direction correctly because you actually SEE it, if more then one person SEES a vapor trail or whatever going up and then a big explosion, it more then likely happened just like that.
When an event happens where we have to pinpoint it based on sound, well it's much harder to pick a direction because you have NO VISUAL contact to find it and the sound doesn't last long enough to be accurate in finding where it might be coming from so the direction that people think a sound came from could be wrong unless the sound is sustained intermittently for long enough for them to pinpoint it.
True, but all the JFK "eyewitnesses" also "saw" gunmen on the grassy knoll.
