Well, I did not post this here; it was an old post from the EF-JFKA.
However, it still is true. Modern guns can and do smoke, depending on ammo, and snub-nose .38s were the default concealed weapon of 1963, and a hand-gun that delivered lots of smoke and noise. Ammo for .38s, then and now, was often "hand-packed" to save money, meaning a smokey brand could be used.
Not one, but two law enforcement officers (DPD'er Smith and Sheriff Weitzman) said they met a Secret Service agent flashing credentials in the GK area in the immediate aftermath of the JFKA, yet the Secret Service says they had no one on the GK, and no other person has come forward and said, for example, "That was me on the GK. I had an FBI badge that looks like a SS badge."
OK, what are the odds both Weitzman and Smith hallucinated the SS-badge waving man? In the exact area where many witnesses say they heard a shot and a smoke cloud? That seems like a long-shot, no?
I have reasonable doubts about the WC narrative.
The official HSCA narrative, that there was a gunsel on the GK, makes more sense.
A gunsel on the GK means a conspiracy.
