"You just don't hear of something like this. Somebody gets shot in the head and they're dead," Byrd said.
It's not that big a deal, and shouldn't be in 2072 because quite frankly very few small-caliber head shots kill immediately. A decent medkit should be able to prevent the trauma from causing death from esanguination and having brain matter ooze out. This is why if you want to kill someone, be sure the use hollowpoints. Besides using a bitch caliber, he was loading a round that isn't going to cause a great deal of trauma beyond carving a .380 diameter hole through the head.
Of course, if you're Kurt Cobain and blow out the back of your skull and destroy everything between the barrel and said skull, then you're fucked.
