2. Along developping technologies comes new concerns about people's privacy. I'm not to much concerned abou it in particular.
Private investigators are people who are paid to gather facts. They usually work for private citizens or businesses rather than for the government. They can get useful information from witnesses and bystanders, sometimes with the help of false pretenses and fake identification. He stalk witnesses, take pictures, search buildings and keeps an eye out for clues that others may have overlooked. On the other hand, since past few years, we may being wached in every corner of the streets. There are many and little devices that can put him through about our single every day life. For example, we can observe some cams hanging on the stree lamps or next to traffic lights. These are surveillance cameras that monitor civil liberties, suspecious incidents, etc. Google earth and google maps are easy tools that we can find on the world wide web that allow us to see what is happening away from our city or country.
