Are we to take your word for the laser thing, or are you going to post your experiment? Surely you would have a video of what you claim...
Yes, I have done the laser thing and, no I don't expect you to take my word for it. The whole point is for you to do it yourself because you wouldn't buy anything I posted anyway. You are a LNer and it's your job to ignore/obfuscate/deny any and all evidence that suggests Oswald was not a lone nut. Are you saying you might change your mind if I post my results? HA!
Everyone should convince themself by doing the simple, cheap experiment that even dufus Myttonhead can do. And it will be the most enlightening experiment you will ever do. But I doubt you will do it, since it might devastate your LNer world.
Here is what you need: 2 cheap leveling lasers (2 x $20), a protractor to set the angle of trajectory and a camera tripod. That's it! Set it all up as shown below:

With the 2 lasers pointed at one another, sit in the chair so that the low laser strikes your throat at C6. Does the high laser strike your back at T1? No? Bend forward so that it does. How bent forward are you? Was JFK bent forward to the same degree? The lasers simulate the bullet's straight line trajectory thru your body. To my knowledge no one has formally done this SIMPLE BLOODY EXPERIMENT which anyone can do, which renders all the CGI models moot. No one buys CAD drawings, but who can deny a deadly accurate re-enactment?
Good luck!
