What's funny Trashman, is that your views on child porn are merely the result of your own upbringing. It's very likely that different upbringings will give people very different opinions on the subject. It's not through some genetic trait that we're supposed to acknowledge 18 as the age of consent and appropriateness. In fact it's quite the opposite, genetically, most people are going to desire to copulate with anyone capable of reproduction. Fear of what others might think is very often the main reason a person won't stray too far away from their own age group. Is there a great deal of different between a 16 year old ending up with a 28 year old, as opposed to a 19 year old with a 45 year old? Yet one is (in most states) illegal, and the other is not. However, when people think of child porn, the connotation that is usually associated is a person who is pre-pubescent. There is not really a logical reason in any society to have a desire for this, and I would probably consider that perverted. However, perversion isn't illegal. I agree with nuclear, the creation and distribution is what should be illegal. I'm tired of illegalizing the ownership of certain things, as a general principle and nothing on the side of ownership of child porn specifically.
On another note, steganography anyone? Should work fairly well, even at a customs inspection. But the smartest idea is to simply keep that kind of data off of anything that could be searched, either access it via the net after getting through customs, or put it on a MicroSD card in your phone (honestly, who looks _in_ a phone?).
