I learned different, the hard way, from a judge. In the eyes of the law, when it comes to sex, if there is opportunity and accusation, then there is a prima facie case.
and your DNA off the maid
Lack of DNA does not prove innocence. It just implies a condom was used. Don't forget, the Duke La Cross players were accused of rape with a broom handle. Does a broom handle leave DNA??
Every man should put some effort into understanding the rape laws in their state and area. Otherwise, you are ripe for the picking.
