Ten years ago, Vlad Teichberg was a derivatives trader on Wall Street. Today, he is one of many protesters who have set up camp downtown to demonstrate against Wall Street and all it stands for.

"Injustice has always pissed me off," said the 39-year-old Russian immigrant who now calls Bushwick, Brooklyn home.

For Teichberg, the answer lies in documenting civil unrest, and he helped to set up the live-stream of the Occupy Wall Street protests on the Web.
