This chapter describes crime completion as a way to interpret success rate; completed crimes are deemed successful and stopped crimes are considered fails. More specifically, acts of terror can be committed in both small- and large-scale plots, with a multitude of elements affecting the plan, execution, and consequence of the attack. The tool, often referred to as weapon choice, is similar to the tactic used in the attack; however, all means do have a cost. Logically, it can be assumed attackers with greater financial backings would attain more appropriate or complex tools for their specific motivations. In the “Analysis of Jihadi Terrorism Incidents,” the gathered information on “links to organizations” can show whether or not completion of crime is more evident in those with group affiliations, versus those who do not. Frequency counts for primary tactic were compared to the binary results of completion of crime.
