As usual, you're way off. Do you know how young the underage woman was? Do you know the age at which the cutoff for that crime is? It isn't 19, 18, or 17. And, not atypically, you use a very dubious source, Facebook, as your reference. Wonderful! And, by the way, being homeless isn't a crime but failing to register as a sex offender is. It doesn't matter if you're homeless or not, you must notify the authorities when you enter a locale. 
Let's let this guy crash in your backyard as you entertain some young female members of your family, Lynn. 
You seem to feel this fellow is some sort of victim, that the police are picking on him. 
Bizarre.
Next time you're in danger, make sure to run to downtown Eugene and ask this guy or one of his friends to help you.
