This just gives an overview.
Supposedly the mask he was wearing was top of the line, expensive boots.
Anyhow, there was a mysterious umbrella man, also the day Kennedy was killed. Sunny day, opened it up as the limo came in. Lifted it high above his head, spun it and moved it east to west. After the shooting, he say down on the sidewalk. They figure he was a signaler and communicator.
Thanks for the info.
