Issue number one: The problematic ways that the prison system deals with assault and mental illness among inmates.
Issue number two: Whether the potential sentence for a crime purely involving speech, rather than actions, should be so severe as eight years in prison.
Issue number three: Whether the speech in question was Constitutionally protected satire, or a criminal threat.
Issue number four: Whether the defendant should have gotten some slack from the justice system -- i.e. why the police/prosecutors/court involved haven't determined by now that lesser charges/penalties are appropriate.
I'm sure there are more.
