So you are suggesting that someone has to be an "expert" on sniper locations to conclude that standing out in the open is not the best place to murder someone and get away. HA HA HA. And using your own logic we must conclude you are in a position to dispute that seemingly obvious point because you are an "expert on sniper locations"? And you are citing as support for this conclusion that members of the alleged conspiracy who were in the open were noticed? And the best way to frame someone shooting JFK from behind is to shoot him from an entirely different location with an entirely different rifle thereby requiring a cover up of the evidence including bullets and wounds (i.e. necessitating access to the president's body and evidence after the fact) when all that complexity and risk could be avoided just by having your fantasy sniper fire the shots from the same location that your fantasy conspirators intend to frame their patsy using the MC rifle associated with him (i.e. the 6th floor window). So entertaining.
This is the same stunt he pulled on me when I said I didn't believe Oswald was a CIA agent. My response that I didn't think Oswald was one came after a number of people claimed Oswald indeed
was an agent. The typical back and forth on who Oswald was sort of exchange.
He then asked me what my firsthand knowledge of intelligence operations was. Not, mind you, the people making the claim but me, disagreeing with the claim. So I cited the judgment of CIA people. Not good enough. Then KGB people. Not good enough. So the original challenge was both silly and dishonest. He wasn't going to accept the judgment of people with actual firsthand knowledge of the issue.
In any case, we have once again the claim that powerful groups (in numerous agencies and with numerous political views, e.g,. Democrats and Republicans, liberals and conservatives, all who hate each other) conspiring to kill the president in broad daylight with hundreds of people watching, many with cameras. And then altering much of the evidence to make it look like the shots came from behind when they came from elsewhere. And then covering this all up. For half a century.
This is sheer lunacy and at some point we have to recognize that we're trying to reason with people who believe in such lunacy. And act accordingly.
