7. Problem of the Camera
 Double-edged sword
 A threat of privacy
 Also another kind of violence
on the right of keeping secret

8. Why people feel unsafe of privacy?
 Everyday life will under watching by camera
 The government does not show how much they got
 What a camera can do is limited
 How long a video is? How long will it being kept?

9. We still need camera
 As it do works in the data shown as the reduce of crime;
 As it do works in saving money for the government
 Life is far more important than privacy
 The one should be responsible for the “threat of privacy”
