A person I know was convicted of child porn.
He was found to have quite a few photographs of naked children, both just nudes and of sexual activity.
The ages of the kids in the pictures were from 3 to 15.
It might be possible to mistake a 15 year old with an 18 year old, especially by just looking at a picture.
There is no way you can mistake a 3 year old for a consenting adult.
The law is binary, and that works out as a bad thing.
30 year old banging a 17 year old the day before her 18th birthday should not be the same thing as a 20 year old raping a 3 year old.
But in the eyes of the law, the crime is the same.
I also am offended by the sexual offenders list. If the SOB is so dangerous he needs to be on a list, his ass needs to be in prison.
