My memory is sketchy, at best...but seems like there was a case where some high school couple were dating in high school. The guy was older and was out of school and over 18 (or whatever the age limit was) and got caught up in a statutory rape deal because she was technically, all of a sudden too young. People thought that was bull and I suppose this change was in response. Don't ask for links or cites, it's entirely possible I'm conflating 2 or more stories -- any permutation of which may not have occurred in Indiana.
Under the premise that if a broadly defined "relationship" exists, is is no longer illegal for an 18 year old to have anal/vaginal/oral sex with his little 14 year old boyfriend or girlfriend and nor is it still illegal for him to film it with his phone. Today, as long as there is a 'relationship' with the little 7th or 8th grader, not only can he have whatever sexual congress he wants, he can also walk around with as many images of junior getting penetrated in as many different ways as his phone can hold.
Who in the world, let alone our legislature, would have voted for that? It is shocking that this got snuck through without news coverage. Maybe it needs to be covered now?
