heat, and blast wave. The heat produced often causes a secondary incendiary
effect. An incendiary bomb generates fire-producing heat; it does not cause
a large explosion when ignited.
b. Bombing. A bombing occurs when an explosive bomb detonates, or an
incendiary bomb ignites.
c. Bomb Threat. A bomb threat is a message delivered by any means; it
will warn or claim the presence of one or more bombs. A bomb threat may, or
may not, specify the location of a bomb; it may, or may not, contain an
ultimatum related to the detonation/ignition or concealment of the bomb.
d. Bomb Incident.
This is any event involving the detonation or
ignition of a bomb.
It can also be the discovery of a bomb, or the
execution of a bomb threat.
e. Bomb-Incident-Preventive Measures.
These are measures taken to
reduce the production and placement of bombs.
Measures are also meant to
reduce the disruptive effect of bomb threats.
f. Bomb Threat Plan.
This is a complete plan which assigns
responsibilities and specific actions to be taken when a bomb threat or
Developing a psychological profile of persons capable
of such anti-social behavior is nearly impossible, since bombers have come
from all walks of life. Also, they have come from various age groups and
differing economic and social backgrounds.
Many bombers are known to be
deranged and/or have character disorders.
(1) The popular idea of a bomb is a black sphere the size of a
bowling ball, equipped with a sputtering fuse.
This is not likely to be
encountered in sabotage by explosion. An explosive bomb itself is the unit
of destruction and it is not dependent upon outside aid as is an incendiary
bomb. Because of these traits, an explosive bomb is normally larger than an
However, the same ingenuity of disguise is applicable.
Five sticks of dynamite taped together and equipped with a blasting cap
would make a capable bomb, but upon sight, this would cause suspicion and
concern. The same five sticks of dynamite stuffed in a suitcase with a dry
cell battery and a clockwork delay device would be just as destructive, but
it would not attract attention. A lump of plastic explosive coated with a
mixture of shellac and coal dust would be unnoticed in a load of coal. The
possible combinations of explosive, activator, delay device, and outside
container are many.

enable a person to make a bomb.
