A good use for surveillance?

I went to the Vancouver Art Gallery's Exhibit for Massive Change: The Future of Global Design. There was a wall hanging that said that 85 million viewers have been made aware of human rights issues through targeted presentations by Witness, an NGO that puts cameras in the hands of activists.

I thought that was an interesting little tidbit, especially after our little downtown surveillance field trip.
