You really should avoid trying to label people stupid & ignorant, in the face of everything you generally present. The only thing I'd be "wrong" about, is that there was a secret service agent with an AR-15, in clear sight of hundreds of witnesses, that AT NO TIME, did ANY OF THEM, observe or witness ANY Secret Service agent either aiming, or even "falling foward" to cause a discharge, that just happened to hit the president seconds after he had just been shot.
Contrary to your ongoing error-riddled positions and claims, I'm actually quite versed in the entire JFK assassination, and the physics don't support just 1 gunmen either. But it also doesn't debunk that the fatal shot very likely came from above, and behind the president....as most witnesses and the science supports
