I think it boils down to each individual's personal experience.
If you live surrounded by people who will hurt you, steal your stuff, or act in reckless ways if they think no one is watching; then pro-surveillance sounds more appealing.
If instead you feel that the people around you will behave even if no one is watching them; then privacy concerns take precedence.
I don't necessarily live in an area where I expect people around me to behave. Most people do and I have some good neighbors, but its also a rural area with a drug problem.
I also don't want surveillance to protect me though. Its my job to protect myself, and ideally to be part of a community that looks out for each other. It isn't the governments responsibility to protect me if said protection comes at the expense of my own freedoms.
I don't want to be a rat in a cage just so I can feel safe.
