“A 27-year-old man and his 26-year-old wife said they heard footsteps at about 4 a.m. Saturday

The couple was investigating the sound when the man was confronted by an intruder armed with a handgun.”

这对夫妇在凌晨四点听见脚步声。
要么是这对夫妇非常幸运，凌晨四点没有熟睡，能够听见脚步声。要么是这家装了监控警报装置，能够把主人从睡梦中吵醒。还有可能是养了狗，能够报警。
看来养狗或者安装监控系统，是防卫成功的前提。绝大多数人在凌晨四点听不见脚步声。
