Did James Simmons See Smoke from a Rifle on the Grassy Knoll?

[John Corbett]

   "Apparently"?  This is exactly the way JFK Assassination Urban Legends are created. Somebody, (such as yourself), hears/reads something, they mynah bird it, and then on down the line it goes. Do your own JFK Assassination research and avoid having to make snappy retorts such as "Apparently".   

If Mark Lane was not trying to make the case that rifle smoke was seen on the GK, just what was his point in even bringing this up.
