So if thinking the adult is a minor makes it a crime, does thinking the mimor is an adult make it not a crime?
No. It doesn’t matter.
In Florida: Knowledge of age is not a defense against criminal charges.
So, if a girl lies to you and says she is 18, 20, or whatever. But is actually 15, or 16. You are still going to prison, do not pass go, do not collect $200 dollars.....ever again.
