I arrived about 8:30, and blundered unprepared into a scene where protesters were being dragged away despite no apparent signs of provocation, tv crews were blocked by airport staff from filming the outrage. All told, i saw about fifteen police vehicles of various types. I managed to get away from the cops and take a few snaps at a distance with a zoom. if they're any good, i'll post them here.
I have no idea what happened to the potential deportee.
