Incident Summary:

04/29/1984: Two members of The Order, Richard Kemp and Bruce Carroll Pierce, placed a bomb in a crawl space under the kitchen near the rear of Congregation-Ahavath Israel Synagogue in Boise, Idaho, United States. The bomb, which was homemade by Pierce and consisted of three sticks of dynamite, an electric blasting cap, a battery, and a timer, caused minor damage to the synagogue's kitchen and heating equipment, in the amount of $4,000. No casualties resulted from the blast, which Pierce later described as an "act of war" to serve "the greater good," even though he initially intended the bombing to be a test of his homemade device. However, the bombing occurred at the start of a week-long national convention to commemorate victims of the Holocaust.

Additional Information The bombing occurred around 4:00pm, and coincided with the start of a week-long national convention to commemorate victims of the Holocaust; Pierce later described the attack as an "act of war" to serve "the greater good." During the trials for members of The Order, the judge stated that evidence about this bombing could not be presented in court, and prior testimony indicated that the bombing had not been sanctioned by Order leaders, it was an act conducted solely by Pierce and Kemp on their own to test the bomb, and other members of the group did not have prior knowledge of the incident; defense attorneys argued that it therefore could not be considered part of a racketeering conspiracy, and thus, it is doubtful that anyone was charged for this crime, but Pierce and Kemp were both later sentenced for their other crimes during their involvement with The Order.
