Parent didn't address it because it doesn't need to be addressed. In most states, the law is not written "it's illegal to have sex with a 15-year-old PERIOD."

Parent didn't address it because it doesn't need to be addressed. In most states, the law is not written "it's illegal to have sex with a 15-year-old PERIOD." Instead, the law is usually "it's illegal FOR AN ADULT to have sex with a 15-year-old." You are correct that -- for states that a) don't have the "for an adult" clause and b) don't have "Romeo & Juliet" clause -- the law as written DOES imply both kids are guilty. And I'd bet the cost of a nice dinner that, in some of those jurisdictions, both kids in a case like that WERE charged.
