For example, some time-series studies report evidence that suggests reduced homicides in the immediate aftermath of an execution.

A second model is that people respond not to the event of an execution but to the perceived probability of execution given commission of a murder, and that the event of an execution causes them to update this perceived probability.

Furthermore, even with a completely specified sanction regime, extrapolation of the findings to other settings or modified versions of the tested sanction regime would require a theory of perceptions and behavior.
