I skimmed this thread, but did the fact that the pistol did not even begin to chamber round #2 come up? Round #2 still in the mag means it was a wrestling match for the pistol, with somebody’s hand or hands wrapped around the slide, preventing it from moving rearward to pick up round #2.
A wrestling match over a gun can’t be murder, can it? With the shooter on his back, getting beaten?
Not in a sane world. Thanks for posting that info. I did a search and found the Massad Ayoob thread you posted.
