San Diego ? With his Darth Vader helmet, black cloak, spikes and light saber, die-hard Oakland Raiders fan Charles Ybarra quickly caught the attention of Super Bowl security screeners.

Police pulled the 30-year-old Fremont, Calif., resident aside, X-rayed his gear, then let him go. Sweating under a warm, San Diego sun, Ybarra wasn’t complaining.

“It’s a beautiful sweat,” he said, adding that his colorful presence was a necessary ingredient for Raider good luck. “They need my spirit.”

They needed more than that. The Tampa Bay Buccaneers beat the Raiders, 48-21, Sunday night.

“We’ve played for this our whole lives. People have booed us, people have laughed at us.” said Bill Shepherd, 31, a Tampa fan who spent a month-and-a-half’s salary on his game ticket. “It’s the best money I’ve ever spent.”

San Diego police made six arrests for minor offenses at Qualcomm Stadium and at least a dozen more in the Gaslamp neighborhood, but said fans were generally well-behaved.

In Oakland, many fans heeded police warnings and avoided the city’s historic Jack London Square, near downtown.

After the game, police broke up crowds of Raider fans who gathered in the streets, in some cases firing tear gas. The action came a week after fans set fires, broke windows and threw bottles and rocks following Oakland’s win over the Tennessee Titans in the AFC championship game.

There were few complaints or problems as fans slowly made their way through a half-hour security line before kickoff that resembled an airport more than a football game.

“We’re ready to get on a 747 and fly away,” joked Steven Friedman, a Raider fan from Los Angeles.

Raider fans outnumbered those rooting for the Buccaneers, but left feeling sheepish.

“Ouch,” said Michelle Dalessio, a 34-year-old Raiders fan from Phoenix. “It was Tampa Bay’s day. I think we got outcoached.”

Buccaneer coach Jon Gruden coached the Raiders for four years before taking over at Tampa this season.

Police were everywhere around the stadium — on motorcycle, on foot, on horseback.

National Guard troops in camouflage fatigues stood guard at a 60-acre fuel-tank complex next to the stadium.

The Goodyear Blimp made a morning flight, but steered away from the stadium as a no-fly-zone went into effect. The ban kept all commercial and private aircraft at least seven miles away.

San Diego police, in charge of Super Bowl security, required all patrol officers to be on duty Sunday. The city was spending about $2 million on security.
