Do We Need More Cctv Cameras?

Year 12 EAL SAC2: Oral Presentation -----------Do we need more CCTV cameras? Good morning Ms Elder and my classmates, today Chelsea and I are going to talk about the CCTV cameras in Australia. CCTV cameras are closed-circuit television cameras transmitting signals to places where filmed footage may be monitored by security staff. In 1981, the first CCTV camera was installed in a major road in Melbourne. Its purpose was to help with the traffic for a forthcoming Commonwealth heads of government meeting. As time goes by, the use of CCTV cameras are gradually changed: they are used in school districts to monitor the activities on school campuses; Businessmen use them to monitor the routine of their employees; and the governments use them as public surveillance. Particularly, in the crime case of Jill Meagher, the footage of CCTV cameras set in the shop provided important evidence in finding the killer. This is very novelty and shows one aspect of the importance of CCTV cameras, but other people think CCTV cameras also have many disadvantages. So an argument comes out: should we have more CCTV cameras?
(Danni): As an opponent, I think footage taken from the cameras may be misused. They have no significant deterrent effect on crimes even give people false sense of security. Moreover, the CCTV cameras are costly to install and maintain. First of all, the footage of CCTV cameras can be misused. In the ABC radio- "PM program", Stephen Blanks said:"We've seen cases where police have unfortunately misused CCTV material or have attempted to destroy CCTV material which exposes polices misconduct." This is sad news and makes us feel CCTV cameras are scary stuffs, we can't do anything when we don't want our behavior to be recorded, but the police could do whatever they want, this is unfair. Also, the hackers would interesting on the footage and put them on the internet to destroy people's privacy. These issues make us concern about that do
