The Swiss refused Monday to extradite Roman Polanski to face rape charges in the U.S., angering the cop who arrested the director three decades ago.

"He should be in jail," fumed former LAPD Detective Philip Vannatter. "I don't care that he won an Oscar. He's still a bad person for raping a 13-year-old girl.

"He should have been tried 33 years ago for rape and sodomy and juvenile drugs instead of plea bargaining down the charges and getting a chance to run. I was against that from day one," Vannatter, 69, told the Daily News.

Polanski, 76, fled to France in 1978, hours before he was to be sentenced for having sex with Samantha Geimer after plying her with champagne, drugs and a promise to feature her in French Vogue.

France does not extradite its citizens, but Polanski traveled to Zurich to accept an award and was arrested. He's been under house arrest for 10 months.

Swiss officials freed him Monday, saying U.S. authorities failed to produce necessary documents and should have sought extradition earlier.

While Vannatter railed against Polanski, Geimer's mom, Susan Gailey, just let out a long sigh.

"I'm happy that it's over. Relief, that's it," she said from Hawaii.

Geimer, 46, and a mother of three, previously told The News she forgave Polanski.

"I have no hard feelings," she said, adding that she just wanted to move on. "I know that he regrets it."

Charlotte Lewis, the British actress who came forward in May with allegations Polanski also abused her, called the ruling "disgraceful."

"The Swiss decision sends the wrong message to others who have committed a sexual crime against a child," she said in a statement.

The Justice Department said it was "disappointed" in the Swiss decision, and denied there were any holes in the extradition request.

The State Department said it continued to "pursue justice" in the case - but Vannatter doesn't think he'll ever see it.

"I thought at some point he'd have to come back and get it over with," he said of the "Rosemary's Baby" helmer. "But he'll never come back now."
