7-year-old Emma Silva of Dartmouth stepped up, ball in hand, took aim and then fired. Splash.

On her first shot, Silva’s toss met its target, soaking Dartmouth police officer Cristina Brum simultaneously with the large bucket of water perched over her head.

“It’s probably the only chance you’ll get to throw something at a cop and get away with it,” Officer Joe Vieira megaphoned to the crowd at the Dartmouth Police Association’s “Concert on the Green” at UMass Dartmouth Saturday night.

The event, which is in its 14th year, featured music from Jimmy Buffet tribute band “Changes in Latitude,” as well as other fun fundraisers like the classic car show and the "dunk-a-cop" event that Silva and Brum had just taken part in.

“It’s a lot of fun,” said second-year officer Justin Medeiros, who was the next in line. “It’s cool now — until I get wet.”

Officer Richard Medeiros, who’s helped put on the event since it started, said it’s things like the dunk-a-cop, the 50/50 raffle, and the sale of food and beverages that help the group raise funds for local youth organizations. Those include groups such as Dartmouth Youth Athletic Association, Pop Warner Football, the Dartmouth Youth Commission and more.

“We pretty much break even with the band,” he said, noting that the turnout at this year’s event was better than average. “The band is fantastic.”

“There’s a lot of activity and a lot of fun going on this evening,” said DJ Gene Daniels, who spun an eclectic mix of hits for the crowd as they awaited the main act.

Richard Medeiros said the car show portion of the event was bigger than ever, with more than 100 vehicles filling the lawn just beyond the amphitheater where the concert took place.

“The car show just keeps getting bigger and bigger,” added Daniels.

Medeiros said that, because the event has gone on for so long and has become so successful, they can provide five college scholarships per year to Dartmouth area students as well as the funds to the different organizations and charities.

“We try not to disappoint them,” he said. “Our main goal is community awareness and goodwill for the Dartmouth Police Department.”

At around sunset, Changes in Latitude came onto the stage, rolling through a number of Buffet’s hits and covers from others, such as James Taylor’s “Mexico.”

Cindy Walker, a self-proclaimed “Parrothead,” or a die-hard Jimmy Buffett fan, made the trip from the Cape.

“They’re great,” she said. “I’ve seen them play about five times, and they never disappoint.”
