and what we heard from the deputy mayor is that the city already even before these attacks, the gunfire, the explosions, perhaps suicide bombings at that football stadium, even before earlier there had been a heightened state of alert in paris, is that right? >> that's absolutely right. we heard from several of the american and other expatriate installations here that in fact security had been quietly but steadily stepped up in the last perhaps week or two weeks. so seems to me that the french had some kind of intelligence that something may be in the works. and as paul was reporting there there was the thwarted attack where the french said they picked up someone who was trying to attack french sailors. so there are clearly there was some kind of noise out there on the terrorist network that put people on alert, put the police on alert here.
