My grandfather fled a certain regime decades ago in order to avoid prosecution. His horrible crime was being born in the wrong race. Sadly my great-grandfather did not have the same luck, and his whereabouts are still unknown to this day. Not fleeing did not really help in proving his innocence. Remember, being innocent is in eye of the beholder.
Anyway, he might be accused of sexual assault but he actually did nothing immoral. He just visited a legal site and had consensual sex with someone who claimed to be an adult at the time, and is in fact an adult now.
