These drawings are ludicrous....They reveal a desperate attempt to make the official scenario believable.
No "attempt" from me to make some "official scenario believable". I'm just showing the physical possibility in one particular 3D model. Let the chips fall where they may.
You, however, seem a bit desperate to disprove
anything the WC or HSCA claimed in regards to a gunman being at the SN.
Referring to the first drawing .... The fore grip of the rifle is not sitting on the box...it appears to be sunk into the cardboard of the box...
The Z223 shot would not work with the crease. Or (maybe a better term) the gouge.
This needed to be done to allow the trigger guard / Magazine to contact the top of the box. The distance from the trigger to the butt plate of a carcano is 13 inches..... Which means that a shooter sitting on a box to the rear and holding this rifle would be leaning forward and his chest would be nearly touching the box and his shoulder would be about 30 inches from the floor.... but the rile butt would be about 38 inches from the floor ( IOW the rifle butt would be above the man's shoulder.
Always making it seem impossible or requiring some "Got Talent" feat of contortion.
And he could not place his left hand beneath the fore grip of the rifle.)
In the scenario, the weight of the rifle would be on "Box A". Pinning the rifle down with the left hand might be more feasible. OK, now you'll claim the scope would be blocked.
I don't know why I bothered to respond to such a ridiculous post.....
May I compare you to H.L. Mencken, Art Buchwald and Harold Weisberg? You're drawn to the absurdity of things. In this topic, the most absurd thing would be that the gouge was caused by the gunman. Look at what's the President today. Life abounds with absurdities and contradictions.
