Helene, if two people came into your store and said "This is a robbery. Give us all your money" wouldn't you feel threatened?
If one (or both) of the robbers "waved a gun in the pharmacist's face" then the threat, it seems to me, is even greater.
"Loaded" is an assumption. Probably correct, but it doesn't matter. Proper gun safety procedure is to assume
all guns are loaded until proven otherwise. Anyway, what difference does it make how many guns were in the store? Maybe there was one by every cash register. So what?
Given the positions of the two robbers when the first shots were fired, it doesn't seem likely the pharmacist was aiming at the guy who had the gun, which makes no sense to me. Most likely he was "spraying and praying", which is typical of people who don't really know what they're doing. Either that, or he took a couple of shots at the gun-toter, missed, and switched to the other guy who for all he could know, also had a gun.
Gerben: I'm not a lawyer, but I don't think the judge gets to make that determination on his own. It would be part of Erslan's defense, presented to the jury, and the jury would decide. Maybe I'm wrong.
