Notice that Holland's drawing is wrong. The correct line of fire goes throo the collar for the 2 guy rods. A multi ricochet involving collar rods pipe (& even the signals) would explain the lead hitting the pavement & the 2 copper fragments ending up in the limo, & 1 fragment glancing off JFK's head.
If Oswald fired a clean miss, there would be a big crater in the road. And no good mechanism for 2 copper fragments to end up in the limo.
My above feb2021 wordage was early in my jfk accidental homicide study. I need to bring things up to date.
Today i know that Oswald's shot-1 was at about pseudo Z112, & ricocheted offa the western guyrod of the signal arm at Z113.
Holland said Z103 i think -- i am happy to split the difference.
Holland i think reckoned a ricochet offa the actual signals.
Today i know that the present owner of the original signals (Christopher) wrote that there is no bullet hole or dent in the signals.
Today i know that the main remnant slug of shot-1 made a keyhole shaped hole in the floor of the limo -- between the Connally's jumpseats.
Today i know that the lead splatter hit jfk in the top back right of his head (vizible in xrays).
Re my wordage that Oswald's shot-2 was at Z218 -- today i reckon it was at Z215-216, & hit jfk & Connally at Z218-219.
Hickey's accidental autoburst of at least 4 shots of his AR15 was at say Z300-Z312 -- hit jfk's head at Z312-313.
Re the pipes at the SN affecting Oswald's shot-1 -- i think the pipes might have affected his shot-2 moreso than his shot-1.
