About five years ago I worked at the Gap in Santa Monica. One of the first things you learn is that the entire store is under surviellance. As soon as you walk into the store, you may be followed by a camera the entire time. Even in the Dressing rooms. After learning this, I started noticing all the cameras in buildings and on the street and everywhere. I don't get paranoid over it, I'm just aware of it.
I saw a movie last night shot entirely from the point of view of surveillance cameras. It's not boring at all! It's like a creepy 'Nashville', with a few different storylines interconnecting. If you want to find out more, visit this website.
