“In the cinema and games that formed the basis of Prax's understanding of how people of violence interacted, the cocking of a gun was less a threat than a kind of punctuation mark. A security agent questioning someone might begin with threats and slaps, but when he cocked his gun, that meant it was time to take him seriously. It wasn't something Prax had considered any more carefully than which urinal to use when he wasn't the only one in the men's room or how to step on and off the transport tube. It was the untaught etiquette of received wisdom. You yelled, you threatened, you cocked your gun, and then people talked.”
