Odd, from watching Sex Crimes Unit on HBO, I learned semen doesn't have DNA in it (only the sperm) thus a guy wasn't prosecuted because the semen left behind lacked sperm so they couldn't get a match. Then I see this article "Thirsty Burglar Drinks Victims' OJ, Leaves DNA For Cops To Find" in the Gothamist (one of my favorite blogs) where a burglar was caught because he drank from an Orange Juice carton and left it behind with his DNA on it (assuming saliva). So let me get this straight, if he were sterile and only ... on the carton he might not have been caught?
ha what do you mean you assume saliva! Last time I checked, urethras were not straws.
