Yeah. Like the "gunman" is going to just casually hang around after killing the most powerful man in the world. There's nothing human about this, because there was no oneshooting from that position, not to mention that, once again, you fail at your ludicrous attempts at producing human figures out of pixels and extremely blurry images.
You are showing us Z219. We see the back of the Stemmons Sign. Where EXACTLY is this alleged shooter supposed to be positioned?
Thanks for pinpointing your shooter's position. So how does JFK and Connally get their bullet Entry wounds from shot(s) fired from that angle? Or, are you claiming that shot(s) fired by that shooter missed?
You're not sure if this guy was a shooter? So why else would he be, "crouched on his knees"?
