@BillRM,
Unlike you I don't obsessively follow different countries' child exploitation and pornography laws. However, I don't think any country's laws are designed to criminalise children, but to protect them from the sort of adults who obsessively follow different countries' child exploitation and pornography laws.
In other words it's a straw man. The example you give is not of a child or teenager, but of an adult. What he does for a living is completely irrelevant. You would have a point if, like some others have argued, you're saying America's penal system is unduly harsh. But you don't, you argue for capital punishment, and have argued that it should still be carried out when there is unexamined DNA evidence that could overturn the guilty verdict.
The example you choose is one of a paedophile viewing child abuse, not the black prisoner in Angola Jail illegally held in solitary confinement since 1971.
Your choice speaks volumes about you. You have no problems with harsh punitive laws at all unless the criminals in question are child abusers, then it's an injustice. You regard the disproportionate amount of black inmates as proof that black people are more criminally inclined, not because your justice system is institutionally racist.
You only care about things that affect you, and harsh sentencing for paedophiles clearly worries you.
You've still not answered the question, because you daren't. It's clearly significantly younger than one day before someone's 18th birthday, just how much is something you're going to keep to yourself because you don't want people to know what you are.
