IMPORTANT CLUE INFORMATION
There appears to be only two reasonable explanations for someone calling to report that a bomb is to go off in a particular installation, and these are :
1. The caller has definite knowledge, or has reason to believe that an explosive or an incendiary device has or will be placed at an installation and they want to minimize personal injury and/or property damage.
2. The caller wants to create an atmosphere of anxiety and panic which will, in turn, possibly result in a disruption of the normal activities and routines at the installation. It should be noted that panic is one of the most contagious of all human emotions and in the context of a bomb threat call is probably one of the ultimate goals of the caller.
