Ever been to a wedding where half the guests are standing and snapping photos as the couple walks down the aisle?
One of the odd features of the videos documenting the current antigovernment demonstrations marking Ashoura in Tehran: it seems that half the people there, including police, are circling the action, holding up their cameras, and snapping away.
One one level, it's a battle of snapshots: Iranians struggling to get their photos out to be viewed around the world; law enforcement targeting people for future persecution. (Gaza too was a war of perception, which continued after the shooting stopped.)
It seems, too, as if the line between participating and recording is disappearing. How long before someone documents his own murder?
