Only a fool thinks sound is a reliable way of determining where a gunshot was fired from. If it were reliable, there would be a consensus. But there is no consensus. My reason for bringing up those who thought the shots came from the direction of the TSBD was to show there was no such consensus. The forensic evidence and an EYEwitness tell us where the shots were fired from. Conspiracy hobbyists don't want to believe that all the shots were fired from the TSBD but since they have no credible evidence of shots from any other locations, they turn to unreliable forms of evidence, like the impressions of earwitnesses.
For starters, how about you tone down the "fool" stuff?
I believe you lean on the 3 hulls far too much. The claim being that 3 hulls = 3 shots. But the fly in that ointment is that the cadence of those 3 shots can Not be accomplished with a bolt action Carcano rifle. An issue that You never mention. We have Umbrella Man/Witt and an adult Amos Euins both on film tapping out the 3 shot cadence. "Pow....Pow/Pow"!
