If the authority's want to push it, technically her lying isn't a defense for Giddy. Now, some states have laws that do offer some protections based on the age difference in situations like this.
For instance, in Pennsylvania, I think there's a 4-year age difference that's allowed. Basically, the law recognizes that it's not uncommon for people of this kind of age difference to date and probably engage in intercourse when they are both minors and it shouldn't go from legal to illegal just because one member in the relationship has a birthday. The courts theoretically could be filled with cases where consensual sex suddenly became statutory rape.
Now, one other thing to consider here, and I know some are going to say it's unlikely, but being unlikely doesn't mean it doesn't happen -- people actually can be a couple and not engage in sex. I know it's reported they had sex, and it's natural to presume they did, but unless that can be ascertained, I'm not sure there's a crime here. I don't think a 19-year-old dating a 15-year-old would be a crime in most states. It's the sex that would make it a crime, or perhaps some other type of blatant exploitation. But, if their relationship is holding hands, kissing, and going roller skating or to the movies and draws a line before intercourse, I don't believe that would be against the law.
