Big Brother and his ever-watchful video-surveillance camera have been around since at least 1984.
But in a new millennium where everybody with a cell phone has a video camera, surveillance has even transcended Big Brother. Not only may government be watching, but the kid walking down the street may be policing the neighborhood. So what's up with that, legally speaking?
In terms of usable evidence, it means that you never know who's going to catch you in the act. Or better yet, get a camera and be prepared to act.
