From The Shyster:

When Terry McGurk hove the brick through the window of Froelich's butcher shop he did it casually, on general principles, and without any idea of starting anything. He had strolled unexpectedly round the corner from his dad's saloon, had seen the row going on between Froelich and the gang of boys that after school hours used the street in front of the shop as a ball ground, and had merely seized the opportunity to vindicate his reputation as a desperado and put one over on the Dutchman. The fact that he had on a red sweater was the barest coincidence. Having observed the brick to be accurately pursuing its proper trajectory he had ducked back round the corner again and continued upon his way rejoicing. He had not even noticed Tony Mathusek, who, having accidentally found himself in the midst of the melee, had started to beat a retreat the instant of the crash, and had run plump into the arms of Officer Delany of the Second. Unfortunately Tony too was wearing a red sweater. . . .
