I came across this video after it was mentioned in a podcast video I watch on youtube.
It's a guy going around with a camera and walking up to people recording them. It's interesting to see how agitated they become so fast.

I don't agree with the guys tactic, especially filming people in private places. But it is interesting watching from an Internet freedom view point. How people seem not to care what their privacy is online. But the moment someone videos them in person they get agitated. I'm reminded of the phrase "if you are not doing anything wrong then you won't mind big brother knowing". It seems in reality most people do mind!
