There are several advantages in having security cameras all over the country. Firstly, there will be a fear factor among criminals, knowing that whatever they do, they will get tracked by the cameras, making them think twice before committing a crime. Secondly, if they really do commit a crime, then it will be easy for the police department to track them down and arrest them, as the cameras would have taken down every single detail of the criminals, and their getaway vehicles as well. Technology has advanced so far that now when a bullet is fired, the cameras will turn in the direction of the gunshot and record what has happened. This is good for maintaining law and order within the country. Thirdly, it gives citizens a sense of security that whoever that might commit a crime will not get away scot-free and will get apprehended.
