Well, I don't mean to cause any problems but it seems the scanners don't have a very good success rate either. They depend on the skills of the person in the viewing room. There have been stories of people sneaking guns past the scanners in testing done by the tsa themselves. Also, many passengers have false anomolies detected and need a pat-down afterward. Dogs are hard working animals that are loyal, bright, they don't complain, and they don't seem to be as mean as some (not all) tso's.
There is no such thing as 100% security anywhere in the world. Even if you stay home and do nothing, there could be a natural disaster and you could die.
