Out of curiosity: if someone hacked this kid's account and posted those comments, and if the legal system is considering the Facebook comments to be his words, what recourse does he have? How does he demonstrate that the speech wasn't his?
If USA has an actual justice system that cares for due process I can't see how anyone involved in these actions can retain a position of any authority within that system.
Interesting point, though.
Note to 4chan. Create screenshots of terrorsm acts from DA and judge and send to other states PD
But I'm pretty sure burden of proof on the prosecution and 'reasonable doubt' went the way of the Dodo years ago.
What if he was hacked by a stupid hacker? Surely facebook keep logs which can be colsulted by the police. What IP address was the comments from? Where were you when the comment was made etc.
