Singapore's zero-tolerance stance and strict narcotics laws have allowed the country to remain safe, secure, and relatively drug-free — which shows that capital punishment does work to deter drug traffickers. The death penalty is essential to Singapore's criminal justice system, and since it is an effective deterrent against drug-related crimes, the public widely supports it.
Those on death row in Singapore are often from the most vulnerable and marginalized groups in the city-state, and executing these people just goes to show that the Singaporean state views them just as disposable as their drug kingpins do. There's no evidence that the death penalty is a deterrent for drug-related crimes or that it has any impact on the use and availability of drugs. Singapore needs to repeal the death penalty.
