Solution/Savior: Camera!

Problem of the Camera

Double-edged sword

A threat of privacy

Also another kind of violence

on the right of keeping secret

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?

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”

The paradox of the camera

The future for camera

Bright because people need it

Need more government work
