Because everybody seems that the movie has no end i'll explain the end here: Farraday's neighbor - Oliver Lang IS a terrorist, and manages to blow up a entire FBI building in which Farraday is killed, by putting the bomb in the car that Farraday rents, and with which he follows the car in which he thinks that Lang has put the bomb, without knowing that the bomb is in his own rented car. Farraday realizes that the bomb is in his car, but only too late. Farraday gets blamed for setting all this by him self and Lang escapes with no one knowing that he is the guilty one and moving in another location, this seeming to be a usual way of operating for him and his wife.
