Subway vigilante Bernie Goetz, who turned down a wrist-slap deal for a day in court on a pot-peddling charge, ranted after his appearance Thursday about the benefits of legalizing drugs.

Goetz, 64, insists that he was entrapped on the November charge of selling marijuana to an undercover cop — and that the police have bigger fish to fry.

“What I think the mayor should do is try stopping all pot arrests for a few months,” said Goetz who turned down a community-service plea deal.

Goetz made headlines nearly 30 years ago for shooting four teens on a subway.
