I am assuming you are trying to argue that the following is applicable:
39-13-101. Assault.
(a) A person commits assault who:
(2) Intentionally or knowingly causes another to reasonably fear imminent bodily injury.
To say there might be a gunman in the area or even to have someone fake like a gunman does not establish that the teachers intended to cause fear of a bodily injury. Imminent? Take out the media hyped fear of a Columbine-type killer on the loose, and suppose the teachers said a killetr bear was loose. Would everyone panic and scream for criminal charges? Why not? Indeed the teachers may have been punking and hoping to cause fear but not fear of bodily injury and certainly not imminently.
It wouldn’t be criminal as a terrorist hoax nor would it be official misconduct.
Well I guess if you can’t say nappy headed ho then you can’t say anything.
What kind of fear does a 11-year-old have from a masked gunman at the door except the fear of imminent bodily injury?
