Xu Zhi Kang(18)--Question 1

I think the cctv is useful as it will help in monitoring the city and help reduce crime rate because the criminals are aware that the police is watching them and if they did anything the police will know at once.

If there was a crime and the suspect is unknown we can just check the cctv to find out who is the criminal. Therefore, making it easier to arrest the criminal instead of investigating all the evidence.
