Team Three
Those gangsters were closing in fast, and more were showing up by the second, converging by the Brass Monkey. It was one part vigil and two parts armed massacre waiting to happen.
As people were converging on that point and trying to get a description of their marks, one looked up at the rooftop of the Princess Bar. Either they thought it was competition from a rival or a gang war threat, they shouldered their rifle and started firing.
Everyone else, thinking that the mark had been spotted, turned and began firing at the rooftops too.
