In Oklahoma, a teenager has been charged with the felony of “planning to cause serious bodily harm or death to another” because he wrote a presumably fictional script for a terrorist strike at a school. He did not show his story to anyone, nor did police searches find any of the weapons &c mentioned.
Updates: The judge dismissed the case on 2003 August 30, holding that no crime exists without evidence of intent to do the violence. Because the dismissal came more than a year after the charge, it could not be expunged; the relevant law has now been changed, effective next week (Nov.1).
