Why so many times?
Why wouldn't you just stop at the X-ray? Is there some method of hiding drugs that wouldn't be very obvious in an X-ray? Ignoring the morality entirely, did they actually gain anything from that? Was there someone who could of hid narcotics past the first 7 steps?
What's so powerful about this story is it doesn't seem to make sense. I want to know why. What on earth motivated anything beyond step 1? Step 1 was bad enough!
