I happened to catch some of the opening ceremony, and I remember seeing a man doing some sort of Parkour on the rooftops of Paris, and ended up standing on top of the Notre Dame Cathedral holding the Olympic torch. He was dressed in middle eastern garb, with a full mask headdress, holding a flame, on top of the Cathedral. I mean, how fitting, an Islamic-esque figure with his instrument of destruction on Notre Dame.
Did you notice he was on a sloped roof?
