The UK is the most heavily surveilled country in the world with more than 3 million surveillance cameras throughout the nation. By far the biggest owner of these is the government, which is a cause for concern for many people. Leaving this aside though, we can see some tremendous benefits from the surveillance program, as well as room for a lot more benefits. A surveillance system can, in some respects, replace much of our police force, and has already done so to a degree. We can attribute much of the reduction in police numbers to the fact that we now have cameras able to surveil the streets, where previously we required police officers on every corner to perform the role. Video recordings are also far more reliable than any human witness, so the information gathering aspect of the surveillance systems is very beneficial to our legal process, as well as our national security.
