Actually, three dead, 27 wounded.
Chicago must have the world's best trauma surgeons. That's one thing they've got going for them.
My buddy was an anesthesiologist in the Navy in San Diego in the ‘80s. They sent him and a bunch of other doctors to LA for trauma training, particularly gunshot wounds and blunt-object head wounds.
He says they got pretty good pretty fast, and while they tried their best, they didn’t feel too badly if one got away. He said it was much better than practicing on pigs, but there wasn’t the pressure of working on military wounded.
