I do not completely agree with that sentence. Based on news reports on the escape on Mas Selamat, Mas Selamat spent most of his of the time in his escape via the drains. As it would be irrelevant to install CCTV in drains, I doubt that installing CCTV would have prevented Mas Selamat's escape.
Quoting from Ming Yao's post: "If Singaporeans are afraid of their privacy being invaded, they really should not worry about it as the security cameras are installed where they can be seen by the public. So, Singaporeans need not be scared unless they committed a crime."
I do not agree with this statement. Firstly the definition of "privacy" has nothing to do with doing illegal activities, as there are legal activities that may not always be welcomed in public under certain conditions. So, Singaporean might feel uncomfortable or insecure if CCTV is placed in public, even though they are not doing anything illegal.
