DECLASSIFIED — EDUCATIONAL USE

single bullet

A browser trig toy. Set the depository window's known geometry, the rifle's own tested cycle time, and the Warren Commission's reconstructed seating plan against each other, and see whether one gunman's line adds up.

Built for 7778777.online, who asked the bot to "prove" the lone-gunman case. What follows is a simplified, illustrative geometry model built from publicly reported Warren Commission / HSCA figures — not a forensic reconstruction, and not a substitute for the actual record. Distances, angles and seat offsets below are rounded for a browser slider, not courtroom precision.

The shot, at any frame

Scrub the Zapruder film. The sniper's-nest window is fixed; the car moves down Elm. Distance and downward angle are read off a straight line between the two — the closer the car, the steeper the shot.

Three shots, one bolt-action rifle

The Warren Commission's own test firers needed a measured 2.3 seconds minimum to work the Carcano's bolt, reacquire the target and fire again — their fastest time, not a typical one. Place three shots inside the frames the window had a sight line, and see if the schedule survives that constraint.

Does one line explain both men?

The single-bullet theory says shot 2 passed through the President's neck and continued into Governor Connally, seated on a jump seat forward and slightly below him. This line reuses the downward angle from wherever you left shot 2 in Exhibit B — change that slider and this angle changes too. Nudge the reconstructed seat gap below — the Commission and the HSCA didn't fully agree on it either — and see whether that angle, projected forward, lands where Connally's wound actually was.

The case for a second gun, and what happened to it

The loudest argument for a shooter on the grassy knoll was never geometric — it was acoustic. A 1978 House Select Committee analysis of a Dallas police Dictabelt recording claimed to find a fourth shot, timed to the knoll. In 1982 a National Academy of Sciences panel reviewed the same recording and found the gunshot-like impulses it relied on occurred about a minute after the shooting, cross-talk from a channel recorded elsewhere — not gunfire at Dealey Plaza at all. No physical, ballistic, or (per that review) acoustic evidence has held up placing a second shooter on the knoll.
