What are the disadvantages of CCT surveillance ?
I think even with CCTV, shoplifters can just cover their faces with a mask. By doing so, I doubt that the police can find out who the shoplifter is. Even with face matching system, they cannot find a exact match. In certain terrorism cases, they often have high-tech gadgets like the camera jammer. If they know where the cameras are, they can jam the cameras temporary. However, enough for the terrorists to escape. Also, even with those CCTV, people can go right under and the CCTV will not be able to see them since the cameras are only build for certain angles. Hackers can also hack into the government system and stop the CCTV from working. I am just trying to state a point that CCTV will not be able to stop the more professional shoplifters/terrorists and will also invade the privacy of others. Installing CCTV will also help the shoplifters/terrorist improve their skills. That will make them harder to catch next time.

By installing CCT, it serves deterrence purpose as potential criminal will think twice before they strike. As mentioned in the above passage that shoplifters can cover their faces with a mask but I think this problem can be solved by deployment ground security guard to arrest the shoplifter once he was spotted in the CCT, red handed. Another point mentioned in the passage is on terrorism. In 2007, the London Subway was attacked by terrorists but the police managed to arrest them with the help of CCT. This again proved that CCT is useful to us. On the point mentioned about invasion of privacy, I disagree. As CCT are mostly installed in public places. If one does not commit any wrong doing, there is no need to worry about being watched.
