Some of these people are drug mules, who have swallowed drugs. Where are the special x-ray machines, like you see in border security shows, at airports? Where are the special R.V. toilets, where they check for drugs, after using the bathroom. Why not just watch them, to make sure, they have a few bowl movements, and not re-swallow the drugs. While they are in custody? Some of these drug mules, think of themselves as jihads to, doing there part in holy war. Wanting your children, hooked on drugs.
