Anticipation of risk, effort and reward [Principle for prevention] People can be influenced to commit an offence by weighing up what they will benefit from it, how much they are willing to risk to commit the offence and what would be involved in committing it. Projects can be aimed specifically at deterring and/or discouraging potential offenders by making the offence riskier, requiring more effort, or have less reward. [Mechanism]
