I'm glad I didn't cause any concern.
I'll take your word for it.
However, in all the excitement, you missed the point which was: Why would Hill (or whoever it was) associate a .38 special with an automatic weapon, even stressing the point using "rather than"?
Exactly what on a .38 special "indicates" they were fired from an automatic?
How about the shells having AUTO stamped on them?
Already discussed half of it. See what happens when you sleep through lectures? If they had 'AUTO" (or "ACP") stamped on them, then he would have said that the gunman had a ".38 automatic" not an "automatic .38." Caliber always comes first, followed by whatever cartridge specifier. If nothing follows the .38, it's generally assumed to be a .38 special, since the great majority of .38 caliber weapons made in the 20th century were .38 specials.*
Anyway, pile up your pillows and feel free to fluff, another lecture ahead:
What Hill said was, "The shells at the scene indicate that the suspect is armed with an automatic .38, rather than a pistol." There are two things in that sentence telling me that he's talking about .38 special ammo. I've just mentioned the first. The second is his feeling the need to explicitly differentiate the "automatic" from a "pistol." No one said that Tippit's killer used a rifle, shotgun, machine gun, sub-machinegun, etc, which rules out the "automatic" being anything other than a pistol. So what did Hill mean when he used "pistol?" It wasn't "automatic pistol;" otherwise, Hill would effectively be saying "armed with an [automatic pistol], rather than [an automatic pistol]," which is nonsensical. That reduces the possibilities to a revolver, a derringer, a single-shot pistol, and a pepperbox, and the latter three are pretty much no-go for various reasons. We're left with Hill saying "The shells at the scene indicate that the suspect is armed with an automatic .38, rather than a [revolver]." So why would he have felt the need to specify that the gun was an automatic and not a revolver? Well, if the shells he had were from a cartridge generally associated with revolvers, and he wanted to avoid confusion. And .38 special was easily the most common .38 out there. So much so --and I repeat myself in case folks can't hear over the snoring-- that saying ".38" by itself is synonymous with saying ".38 special"
The question is then, why did Hill think that the gunman was armed with an automatic? Been over this, too, but will rehash it in case you slept through that one. Hill would later say that he thought the killer used an automatic because of the way the shells were spread out. Personally, I think that the witness statement that the perp had a ".32 dark finish automatic," which had already been broadcast over the radio. Since no one other than Tippit had was ever closer to the gun than 20-30 feet, I doubt that Hill would have put much credence in the caliber being ID'd from a distance. So, he's left with a description of a small, dark finish auto pistol, the .38 shells, and no second gunman or second pistol. Ergo, "automatic .38 [special] rather than a [revolver]"
