Are law enforcement cameras an invasion of privacy?

      After the 911 happened, the terrorist threat has been headache for most of the western countries. Therefore, the governments order more and more cameras to be installed around in aims to monitor the well-being of some important spots in case of terrorist activities, which however raises the concerns over the abuse of power as invasion of privacy by law enforcement.But if this action fully expose to legitimate process, the benefits with respect to the safety of the public will definitely overweight the concerns of the invasion of privacy.
      To protect people from the threat of terrorists is the government's obligation. Increasing the number of cameras around some important facilities such as power plants, airports, expressways and train stations is very necessary because these are not only the most common terrorist targets, but also the way for crime to get away. Without the help of cameras and satellites, it undermines the ability of police department to carry out effective plans to prevent terrorists and bring the murders into justice. Moreover, it is widely believed that the terrorists could have the identification as a legal citizen. For the sake of the security of the society as a whole the police has to be provided with the right to monitor any suspect, no matter he or her is a legal citizen or not. Surely people would have be angry about the fact that they can be monitored at any time or any place. Actually to limit the power of law enforcement, we can enact a legislation to make sure that any action suspected to violate people's privacy has to be in line the law.Sometimes,individual benefits have to give way to the that of the public.
      The surveillance equipment is totally out of the need for government to counter terrorist activities which I believe could bring much more damage that the underlying invasion of people's privacy. Let's make effort together to protect our country, for our own sake and the offspring's.
