However, people install security cameras in their own homes all the time---some of which are even wired to cloud services or outside security monitoring agencies. I agree that privacy exists alongside security. Where the balance-point is best placed varies from person to person. In public spaces not scoped for private activities (such as the streets of a city), the balance point has to be agreed upon by the citizenry in general and is almost certainly somewhere past both "toilet stall" and "personal residence" in terms of collective value for surveillance. After all, we already put up security cameras on street corners.
