My opinion is fairly simple:
Why should somebody be held criminally liable for the *suicide* of Megan Meier?
"Instead, he said he would instruct the jurors that the case is about whether Drew violated the terms of service of the MySpace social networking site, not about whether she caused the suicide of Megan Meier."
The defense lawyer says, and I agree, that this case will never be understood as break of user agreement, but about the ensueing suicide...
This can only go wrong as far as I can see.
You give her a standard penalty somewhere around perjury/signing leases/signing bad cheques ---> The public's reaction will be outraged because a "murderer" got off so lightly.
You give her a severe punishment, and you're creating a weird precedent for further "Internet Law" trials.
Maybe invent a modern version of the pillory for these adults. Adults that really should have known better?
(hurray, I learned a new word today - pillory
