In this dynamic and rapidly changing environment, the Singapore Police Force’s core function is to protect the people who live in Singapore from crime and all manner of criminal harm. Crime in SPF’s context include terrorism and public disorder. In order to achieve this, we apply the strategies of Prevention, Deterrence and Detection. As crime is generally defined by the inclusion of two key ingredients: mens rea (the guilty mind), and actus rea (the guilty act), the twin strategies of Prevention and Deterrence act to deny these two key ingredients of crime; the former strategy stops the criminal intent from being formed, while the latter denies opportunities for the criminal act to be realised. The final strategy of Detection is a mitigating strategy that reduces the damage resulting from the crime.
