State law enforcement officials will closely monitor the situation at Harvard and nearby campuses, and are prepared to offer back-up personnel, said Peter Judge, a Massachusetts Emergency Management Agency spokesperson.

“Knuckleheads who grew up in New Jersey and have been in the area for six weeks should not utilize this opportunity to flip something over,” Judge said.

“I think riots in Harvard Square after we won the division series were under control, and I don’t see any danger in the future,” Jonathan S. Meltzer ’07 said as he watched yesterday’s game in the Weld Hall common room.

“Granted, I’m going to flip a couple of cars when the Red Sox win the World Series,” said Meltzer, a Cambridge native.

There is no recent precedent for sports-related rioting in Boston. Students celebrated in an orderly manner when the New England Patriots won the Super Bowl in 2002, Catalano said.

But then again, there hasn’t been as prime an opportunity—at least since 1918.

Some in Massachusetts are reaching farther back in the annals of regional history for guidance—all the way back to 1692 and the Salem witch trial.

“No Yankee fans were discovered after extensive background checks of the HUPD staff,” Catalano said.

But according to Kidd, one Harvard administrator—whom she identified only as “a new hire”—has been identified as a Yankee fan.

“This person has been ostracized,” Kidd said.
