I think the kid puts it best (and ironically in an extremely mature way) when he talks about how a split second decision screwed it all up. We talk about underage and minors because we are a lot older - but forget that to them that age divide is non-existant. At home with the guys, testosterone going, recieve a text from a girl that sounds a bit sexy - hey we've all done it. Difference is where it's "allowed" for us - for them it, apprently, isnt. Leaving the images on screen or w/e is, obviously, very thick but I struggle to see a serious crime. The boy's parents approach seemed the best of the lot......
Yes, nail whoever actually posted them publicly online (and perhaps lightly reprimand the guy for leaving his inbox open). That is the real crime - regardless of the age of the victim.
