Wow, take a deep breath and calm down.
I want to help you, I really do but you're raving like a Maniac and making no sense.
First of all, give me all your sources(testimony, film, photographs, etc) from where your belief that a man "wearing only a WHITE shirt from the waist up" originates?

I can't believe how patient you're being.
There is literally nothing more you can do to show Royell what a buffoon he's being.
The three synchronised films show that the man running up the stairs is the man who was one of the three stood on the steps.
I would further add that I believe this man is the young black man Sitzman sees with his wife on the bench. It appears that just before the motorcade arrives he walks down to the steps. The moment he sees JFK's head explode he races back up the steps to where his wife and child are, grabs them and takes off behind the pergola, breaking a Coke bottle in the rush.
I don't want to tell Royell there is no White Shirt Man, it's like telling a kid there's no Santa.
