Not a long process—there aren’t many. Behind me is a wall. It has a door in it to my right—a heavy metal fire door of some kind—which might or might not be locked. To get to the door, I’ve got to move toward the two pros moving slowly down the alley, then expose myself for a few seconds while opening the door. Just a tick or two, but it’s more than enough to take a few hundred grams of steel-jacketed lead. And that’s if the door’s not locked ... Pass, thanks.
