fair?

The law is create to give everyone fair justice, but is the law clear itself? Juan Martin is now 30 living under the a bridge of Miami because of a crime he convicted 12 years ago. Back when he convicted crime he said he didn't, he was only 19, who flash a 16 years old and was sent 2 years in jail. He now has a criminal record that show's he's a sex offender forcing him to call under bridge home. How is flashing a teenage girl, when you are only 19 the same as child pornography, rape, statutory rape, and child sexual abuse? Justice is just not clear.
