A covert listening device, more commonly known as a bug or a wire, is usually a combination of a miniature radio transmitter with a microphone. The use of bugs, called bugging, is a common technique in surveillance, espionage and in police investigations. A bug does not have to be a device specifically designed for the purpose of eavesdropping. For instance, with the right equipment, it is possible to remotely activate the microphone of cellular phones, even when a call is not being made, to listen to conversations in the vicinity of the phone.〔〔〔〔〔 == A wire == A "wire" is a device that is hidden or concealed under a person's clothes for the purpose of covertly listening to conversations in close proximity to the person wearing the "wire". Wires are typically used in police sting operations in order to gather information about suspects.〔Informants and Undercover Investigations: A Practical Guide to Law, Policy, Dennis G. Fitzgerald, CRC Press, Jan 24, 2007, page 204〕 The act of "wearing a wire" refers to a person knowingly recording the conversation or transmitting the contents of a conversation to a police listening post. Usually it's accomplished by some sort of device that is attached to the body in an inconspicuous way, such as taping a microphone wire to their chest. "Wearing a wire" by undercover agents is typical plot element in gangster and police related movies and television shows. A stereotypical move scene is when someone is suspected of "wearing a wire", the criminals will tear the suspect's shirt open hoping to reveal the deception.〔Guide to Writing Movie Scripts, Wils Randel, 2009, page 123〕 When infiltrating a criminal organization a mole may be given a "wire" to wear under his or her clothes. This wire device transmits to a remote location where law enforcement agents monitor what is being said. Wearing a wire is viewed as being risky since discovery of a hidden wire by a criminal could lead to violence against the mole or other retaliatory responses.〔Organized Crime, Micheal Benson, Infobase Publishing, Jan 1, 2009, page〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Covert listening device」の詳細全文を読む スポンサード リンク
