Many officials argue against body scanners because they believe that they will not help in minimizing dangerous activity. According to BBC news, airport body scanners will not be able to detect explosive devices used by many terrorist groups. This is because scanners cannot detect liquids or plastics. The scanners are mainly used to detect irregularities on a person's body (bbc,2010). That being said, liquid explosives can still make it on to a plane without being detected at all. Another concern is the fact that although scanners will detect mostly everything that you have under your clothes, it cannot detect what is hidden in your body cavities. This is a main concern because that is a method commonly used when someone is attempting to smuggle something prohibited (Israel,2010).
