CCTV Camera: good or bad?

I would appreciate any feedback on the following essay.

In many cities the use of video cameras in public places is being increased in order to reduce crime, but some people believe that these measures restrict our individual freedom.
Do the benefits of increased security outweigh the drawbacks?

It is true that video surveillance has become commonplace in many cities in recent years. While I understand that critics may see this as an invasion of privacy, I believe that there are more benefits than drawbacks.

There are two basic reasons why some individuals maintain that people’s privacy might be in danger if surveillance cameras are installed public spaces. First, it is unclear to the general public where and how the footage that is being recorded by the surveillance systems is used. There have been some cases, especially in dictatorship regimes like China, that governments used CCTV footage to identify and arrest government oppositions, which are fundamentally against individual freedom rights. Second, protecting the databases in which people’s video footage is stored would not be an easy task for the authorities because this kind of information is exactly what criminals are after, and if they gain access to this data, they may use it to blackmail citizens.

Despite the invasion of privacy that may happen by using security cameras, I still believe these devices are vital for maintaining safety in society. Unfortunately, nowadays more than ever before, cities are attacked by suicide bombers and terrorists. If there are no cameras installed in train stations, crossroads, shopping malls, it would be considerably more difficult to identify and, subsequently, arrest these terrorists. There would be no images to identify them in the first place. Furthermore, the presence of a CCTV camera by itself has proven to reduce crime rates as offenders might be unwilling to commit a crime if they realize that a camera is recording them while they are committing an offence.

In conclusion, it seems to me that the advantages of having cameras placed in public places outweigh the loss of privacy that might occur since we live in an era that crime rate is on the rise.

Very good!
