Niagara Falls officials on Tuesday identified the man who remains in critical condition after being shot by police Friday, as well as the officers who shot him. Reginald D. Barnes was shot during an encounter with police behind a Rite Aid on Niagara Falls Boulevard in a scene captured on police-worn body-camera video. Police released about 30 seconds of the video, which showed Barnes pull a knife and charge at an officer who had just deployed his Taser. Barnes and the officer who deployed the Taser briefly struggle, during which the officer was bitten on the arm and suffered a knife wound to his back, city officials said. Two officers fired their handguns. Officials declined to say how many shots were fired, how many times Barnes was shot or where on his body he was shot. Barnes, 29, is Black and the officers are white. The officers who fired their weapons were identified as Lt. Joseph Scibilia and Officer Greg Paul.
