What are the disadvantages of CCT surveillance?

There are many disadvantages of CCT surveillance, one thing is privacy, with so many CCT surveillance around, it is nearly impossible for people on the streets to find a place where privacy is given. Another disadvantage of CCT surveillance is terrorism, if terrorists were to really take control of all main utilities and CCTV's it would cripple the economy as terrorists can look out onto the streets without being there and monitor every movement the police makes and the terrorists would know how to counter them. Hence, it is better to put more police patrolling the streets and use old-fashioned convex mirrors to look around corners rather than CCTV's.
