Martial artist and actor Jackie Chan has revealed his support for the death penalty for some drug smugglers.

In an interview with journalists, he said, “On some issues, I do support the death penalty.”

“When you’re hurting thousands and thousands of young children, I think these people are useless. You should get the right punishment,” he said.

This comes months after his son, Jaycee, spent six months in jail for “providing shelter for others to abuse drugs.”

Chan is Singapore’s first celebrity anti-drug ambassador and named the official Narcotics Control Ambassador by the Chinese police in 2009.
