The reason we are doing these types of pat downs and using the advanced imagery technology is trying to take the latest intelligence and how we know al Qaeda and affiliates want to hurt us, they want to bring down whether it is passenger air craft or cargo aircraft.
We put people of concern on the watch list or the no-fly list, so we have a number of layers of security beyond the airport checkpoint. We gather as much information about a passenger as the law allows without profiling.
