Not to be morbid, but I would very much like to know, what bullets were used, ball or hp, how did they perform, where were hits made in the bodies, was the officer wearing her vest? ( I hope so ), Did any of the bullets penetrate the vest if worn? Of those who died, where were the hits made? This is unfortunately the 1st real try out for the cartridge on any kind of measurable scale in real life.
I like big calibers as much as the next guy, but high capacity lets you stay in the fight longer, all things being equal. That's why #1 fighting pistol is the Glock 21 or 20 for me, but sometimes too big to carry on my person.
