One police officer reveals that when they handle cases now, they listen and watch. First they use phone system records of victims 'emergency calls to determine the scene of the crime, then they scrutinize the video recorded by cameras in the vicinity to find possible suspects.
一位警察透露，現在辦案靠的就是「二監」──「監視」與「監聽」：先利用受害者通聯記錄找出地緣關係，再調閱附近的監視器錄影帶，過濾可能的嫌疑犯。
