Firstly, it could be argued that when it comes to communication and the advancements in computer utility within the industry, people are becoming too independent on computers a less active. For example, simply clicking a button on a computer rather than sending it traditionally via a post office can now send mail. Although there is a degree of dependence on a computer, it does support the idea that it is time efficient, especially if sending important documentation such as a fugitive's identification to another city, state or country. In addition, although there is a risk of interception of mail on the Internet or a computer malfunction, by the time the same letter could reach its destination, another email could be sent from another computer within minutes. Other sources of communication other than email is faxing machines and cellular phones although are interconnected to a computer are time efficient.
