"..already proven possible..because it happened". Not very scientific or logical of you to see no need for a re-enactment, and don't call me Shirley.
What the laser experiment demonstrates to you is that at the moment that JFK was struck by the MB it could not have taken a straight line path into JFK's back and out his throat if the shot came from the 6th floor of the TSBD. Otherwise, conduct the experiment yourself and prove me wrong. Don't just tell me I'm wrong because you don't understand the experiment.
Given the angle of the MB thru JFK, its only valid trajectory was from the 2nd floor of the Dal-Tex building. You asked.
Why are you so convinced that nobody on here understands the concept of your experiment? I do understand it but, as stated elsewhere on this topic thread, it's impossible to re-enact a once in infinity occurrence.
Assuming that you did get President Kennedy's posture correct, your laser experiment then presumes that absolutely nothing interfered with the bullet's trajectory from the moment the shot was fired until the bullet exited the President's throat. A laser cannot measure the exact angle the bullet left the rifle, the conditions in Dealey Plaza that day, how the bullet reacted when ripping through live human muscle and flesh, etc. Even the most unbelievably minuscule slight movement would effect the outcome. The reaction of a live bullet traveling through a live human body cannot be measured by a laser and even shooting a live person through the back of the neck from the same angle wouldn't have the same outcome. It just doesn't work like that.
It already happened, that's it you can't recreate it. You can't ask someone to re-enact something like this.
Conspiracy theorists don't believe two planes flying into the World Trade Centre would cause both towers to collapse but it happened. I suppose you'd ask someone to re-enact that t prove it's possible too?
