At this point, I haven't studied the technology of the body scanner myself. I'm vaguely aware and have looked at some things, and my sense is that if people were carrying, the body scanner would pick it up. I'm not clear. I need to look into whether it would detect things concealed in a body cavity. I'm not certain. My understanding is that drug dogs generally will pick up what is concealed and will sit.
