Right; that statement confused me too.
It's okay to threaten high-ranking officials of state and local government?
It's okay to threaten prominent personalities?
It's okay to threaten ordinary people?
I think Skins like franksolich says no, it's not okay, but my fellow alum, unlike franksolich, sometimes has problems expressing himself via the written word.
