RS-
My layman's guess is the second shooter was in the Dal-Tex building or the TSBD6. But who knows. There is a strange event in the TSBD4 floor, that I will post about later.
The wounds to JFK and JBC suggest the shooter (s) was/were above and behind.
I suspect there was a diversion at the GK smoke-and-bang show.
The fact remains no one was apprehended 11/22 except LHO, and he was dead two days later.
So LHO's confederates could be anybody. KGB, G2, CIA, Alpha 66, Cuban exiles, Mafia.
The feds did not want LHO's links, domestic or foreign, to be tracked.
But...mostly foreign. WWIII.
I think the JFKA research community may be stretching matters in trying to exonerate LHO. The guy took a potshot at Gen. Walker. Human nature is not always explicable.
