Attorney Darnell Crosland announced plans Wednesday to sue the Bridgeport Police Department for $40 million, saying "compelling new video evidence shows conclusively that Dyshan Best did not have a gun" when a Bridgeport police officer shot him to death March 31. "In Black communities, the protocol is to shoot first and ask questions later - and Dyshan was shot down like a dog," said Crosland, who represents Best's family. Crosland made the remarks during a press conference in his Stamford office Wednesday. The Office of the Connecticut Inspector General told News 12 Wednesday they're conducting their investigation "in a thorough and impartial manner," and that they stand by their preliminary report. On Friday, the inspector general said a 9 mm handgun was found next to the spot where Best fell after being shot. Bridgeport Police Chief Roderick Porter said last week the evidence shows the fatal shooting was "in line with the state's use of force policy." The shooting took place in a driveway in the 1400 block of Kossuth Street after a foot chase, officials said. "The shooting is consistent with what we're seeing across the country - police officers shooting unarmed Black men," Crosland said. "Dyshan had no gun - and so people are really getting close to questioning whether this gun was planted," Crosland said.
