We already have data about other 13yr olds not raping, so it's completely illogical to attempt to use pornography as a scapegoat.

Exactly, the vast majority of 13 year old boys have watched porn of some description. The vast majority of those boys (and we're talking something like 99.9999%) DON'T end up raping their sister.

It was not "caused" by porn (and certainly not the fact that the porn was on an Xbox, seems purely incidental?), watching porn may have put the idea in his head that specific day but the compulsion - actually thinking "yeah that sounds appealing" and going through with it, the lack of empathy - were clearly pre-existing parts of this boy's character either through mental disorder or something major that's happened in his past like abuse. No two ways about it. Normal teenagers dont rape their kid sister no matter how much porn they've watched. He is disturbed and would inevitably have ended up hurting someone, someday.

Also, calls for parents to be watching and controlling what their 13 year olds are up to 24/7? Nooo! It's an awful idea. Keeping short reins on a teenager and having hawk eyes on them at all times is more likely to CREATE an emotionally disturbed adult in future than prevent one. Teenagers need space and independence and privacy - it's psychologically essential. The more people realise this, the fewer emotionally and socially retarded adults we'll end up with.
