(b) It is not a defense to a prosecution under this Section that at the time the defendant made the terrorist threat, unknown to the defendant, it was impossible to carry out the threat, nor is it a defense that the threat was not made to a person who was a subject or intended victim of the threatened act.

(d) In addition to any other sentence that may be imposed, the court shall order any person convicted of making a terrorist threat involving a threat that a bomb or explosive device has been placed in a school to reimburse the unit of government that employs the emergency response officer or officers that were dispatched to the school for the cost of the search for a bomb or explosive device. For the purposes of this Section, "emergency response" means any incident requiring a response by a police officer, a firefighter, a State Fire Marshal employee, or an ambulance.
