Hello! I'd be grateful if you could you check my discursive essay. Thanks in advance! (Part 1) Topic: Some people argue that surveillance society is a threat to civil liberties, others think that CCTV cameras are not an invasion of privacy. Discuss it and give your own opinion. __________________________ The 21st century has brought a myriad of technological advancements. These new technologies are not coming without their own set of costs, though. Today, we find ourselves in a world of ubiquitous surveillance, where everything is collected, saved, searched, correlated and analyzed. Some people contend that CCTV cameras encroach upon our liberty, others do not consider this an invasion of privacy. To begin with, surveillance has been around for centuries. Eavesdropping, stalking, of course, was done with no electronic devices unlike these days. Nowadays using surveillance cameras in public places plays an important role. They provide a sense of security to people, protect property from theft and vandalism, help the police investigate unlawful activity such as murder, mugging, kidnapping, arson and find criminals quickly. For instance, there are a plenty of television programs about crimes where such cameras played a substantial role in the fight against crime. Furthermore, CCTV cameras act as a deterrent to crime because if people know that they are being watched and recorded they will not have a keen desire to commit a crime. It has a positive influence not only on the crime picture but also on the self-consciousness of the whole society. What is more, a surveillance camera can operate 24 hours a day, seven days a week, 365 days a year without taking any break. They are, in fact, also cost-effective and unobtrusive. Authorities do not need to spend large amount of money on police or security. This is the cheapest strategy for law enforcements and security officers than any other crime prevention strategies.
