The bomb was similar to the device used in a bombing at Twin Lakes High School two weeks earlier (197101260001). The car of the Palm Beach County's Superintendent was bombed three months later (197105120002). There were many instances of racial strife at the high school, and, one month before the incident, a white person was appointed principal of the district, despite the recommendations of a biracial committee. The bomb was set explode at 3:00 PM but the timing device malfunctioned. |

Criteria
Criteria 1
The act must be aimed at attaining a political, economic, religious, or social goal. In terms of economic goals, the exclusive pursuit of profit does not satisfy this criterion. It must involve the pursuit of more profound, systemic economic change.
Criterion 2
There must be evidence of an intention to coerce, intimidate, or convey some other message to a larger audience (or audiences) than the immediate victims. It is the act taken as a totality that is considered, irrespective if every individual involved in carrying out the act was aware of this intention. As long as any of the planners or decision-makers behind the attack intended to coerce, intimidate or publicize, the intentionality criterion is met.
Criterion 3
The action must be outside the context of legitimate warfare activities. That is, the act must be outside the parameters permitted by international humanitarian law (particularly the prohibition against deliberately targeting civilians or non-combatants.
Doubt Terrorism Proper
The existence of a "Yes" for "Doubt Terrorism Proper?" records reservation, in the eyes of GTD analysts, that the incident in question is truly terrorism. Such uncertainty, however, was not deemed to be sufficient to disqualify the incident from inclusion into the GTD. Furthermore, such a determination of doubt is subsequently coded by GTD analysts as conforming to one of four possible alternative designations: 1) Insurgency/Guerilla Action; 2) Internecine Conflict Action; 3) Mass Murder; or 4) Purely Criminal Act.
Alternate Designation
The determination of "yes" for "Doubt Terrorism Proper" by GTD analysts is coded as conforming to one of four possible alternative designations: 1) Insurgency/Guerilla Action; 2) Internecine Conflict Action; 3) Mass Murder; or 4) Purely Criminal Act.
Successful Attack
Success of a terrorist strike is defined according to the tangible effects of the attack. For example, in a typical successful bombing, the bomb detonates and destroys property and/or kills individuals, whereas an unsuccessful bombing is one in which the bomb is discovered and defused or detonates early and kills the perpetrators. Success is not judged in terms of the larger goals of the perpetrators. For example, a bomb that exploded in a building would be counted as a success even if it did not, for example, succeed in bringing the building down or inducing government repression.
