What principle dictates that punishments should be certain, swift, and severe enough to deter crime?

The principle that dictates punishments should be certain, swift, and severe enough to deter crime is rooted in the concept of deterrence theory, which is primarily aligned with the idea of focusing on the crime, not the criminal. This approach emphasizes the actions and behaviors that lead to criminal activity rather than the individual characteristics of the offenders.

Deterrence theory suggests that if punishments are reliably administered (certain), delivered without delay (swift), and sufficiently severe (proportionate to the crime), they will discourage individuals from committing crimes in the first place. The focus is on creating a legal framework that acts as a deterrent for potential offenders by making the consequences of criminal behavior clear and impactful. This theory is foundational in many aspects of criminal justice policy and is reflected in laws and systems designed to prevent crime through the fear of punishment.

In contrast, the other options explore different dimensions of the criminal justice system, such as rehabilitation or the underlying characteristics of individuals who commit crimes, rather than the immediate and specific nature of the punitive response to criminal acts.
