Last week in Rome, a Chinese shop owner named Zhou Zeng, his wife Lia and baby daughter, Joy, six months old, were leaving their store when two men whose faces were hidden by motorscooter helmets held a gun at them and demanded the take. The wife, who speaks little Italian, instinctively gripped her handbag tighter; the husband shouted. One of the two masked gunman responded by shooting to kill. Both baby and husband were killed.
