Look, let's keep it 100. Just because an island is full of historic cobblestone streets and wealthy tourists rolling off the high-speed ferry doesn't mean real-life drama doesn't go down. On Tuesday morning, right in the middle of the ritzy downtown district near the South Beach Street ferry docks, two working-class guys got into a heavy dispute that ended with one man in the hospital and another locked up in cuffs.

Kemar Downer, a 40-year-old brother working for Sayle’s Seafood, was dragged into Nantucket District Court on Wednesday morning. The state is trying to hit him with two serious charges of assault and battery with a dangerous weapon causing serious bodily injury. They ended up letting him out on $2,500 bail, but they strapped a GPS monitor to his leg and told him he’s got to stay 25 yards away from the other dude's house.

But Downer’s lawyer, Rob Moriarty, isn't sweating the prosecution's story because he says the eye in the sky don't lie. Moriarty told reporters that the police security video of the fight is an absolute game-changer for the defense, showing what he called "complete and total self-defense."

According to the defense, a bigger dude who works for Reis Trucking decided to slide up on Downer from behind. No warning, no fair fight—just a straight sneak attack. The video reportedly shows this larger guy punching Downer three times in the back of the head, knocking him off balance while he was bent over. Then, while Downer was down, the aggressor started kicking him repeatedly. That’s when Downer did what he had to do to survive: he pulled his knife and defended himself. The whole beef was apparently "over a girl," proving that relationship drama can get you caught up no matter where you're at.

Instead of treating Downer like a man who just survived a violent, cowardly ambush on the job, the Nantucket police immediately treated him like the villain. And to make it worse, his lawyer says the police decided to play dirty with his rights. Moriarty argued in court that the police held Downer overnight on Tuesday instead of letting him get arraigned right away. He said the Nantucket police basically decided they were not going to abide by the Constitution because they think they’re above it. That’s typical behavior from small-town cops who think they can write their own rules when they're dealing with working-class people.

This whole situation is crazy because it's happening right where the rich and powerful vacation. You got families stepping off the ferry with their beach bags at 10:23 a.m. having to witness a raw street-level struggle. At the same time, local leaders like Nantucket GOP head Toby Brown are complaining about security and calling for more vetting after federal agents from ICE and the DEA made arrests on the island.

But at the end of the day, this case is about a man's right to protect his life when he gets jumped from behind. If the video shows exactly what the defense says—a larger man sneaking up, throwing punches to the back of the head, and kicking a man while he's down—then Downer had every right to use whatever he had to get that attacker off him. We’ll see if the court actually respects the law and the tape, or if they’re going to let these small-town cops get away with violating a working man’s constitutional rights.
