At least nine people were injured and 44 people arrested in a second night of violent protests in Charlotte, North Carolina, the city's police chief said yesterday following the fatal police shooting of a black man this week. One man remained in critical condition after being shot late on Wednesday, said Kerr Putney, the chief of the Charlotte-Mecklenburg police. Police used teargas, rubber bullets and flash grenades to disperse demonstrators, who looted stores and threw rocks, bottles and fireworks.Officials said the victim was shot by a civilian, but Putney acknowledged yesterday some claims that he was shot by a police officer."We're investigating to find the truth, the absolute truth as best as the evidence can show us," Putney said.Four police officers suffered non-life threatening injuries, city officials said. After violent protests, Charlotte police won't release shooting videoPolice in Charlotte do not plan for now to release a video showing the fatal shooting of a black man by officers that has sparked two nights of violent protests in North Carolina's largest city, the department's chief said on Thursday.The latest trouble erupted after a peaceful rally earlier in the evening by protesters who rejected the official account of how Keith Scott, 43, was gunned down by a black police officer in the parking lot of an apartment complex on Tuesday afternoon.The killing was the latest in a series of controversial fatal police shootings of black men across the US, sparking more than two years of protests asserting racial bias and excessive force by police and giving rise to the Black Lives Matter movement.Scott's killing marked the 214th of a black person by police this year, according to Mapping Police Violence, an anti-police violence group.Authorities say Scott was wielding a handgun and was shot after refusing commands to drop it. His family and a witness say he was holding a book, not a firearm, when he was killed. Unrest flares anew in US city after police shootingA second night of race-related clashes in Charlotte, North Carolina has left one protester on life support, with the renewed violence prompting the governor to declare a state of emergency.A spokesman for the Charlotte Fraternal Order of Police told CNN yesterday he had seen video from the scene showing Scott holding a gun."It is important that we have a full and transparent investigation of the original incident," Charlotte mayor Jennifer Roberts told a press conference.The pleas went unheeded. Overnight protesters smashed windows at a downtown Hyatt hotel and punched two employees, the hotel's manager said.The slogan Black Lives Matter was spray-painted on windows.Looters were seen smashing windows and grabbing items from a store as well as a shop that sells athletic wear for the Charlotte Hornets."We had a lot of looting at a lot of businesses," Putney said, adding that state police and National Guard troops would help to secure the area. BILL TRUMPS DONALD ON CRIMENew York City mayor Bill de Blasio warned Republican presidential candidate Donald Trump yesterday against embracing the "stop and frisk" police tactic which, he said, would worsen relations between police and the community.Trump praised the anti-crime tactic in which police stop, question and search pedestrians for weapons or contraband and said it "massively changed" the crime statistics in New York City.But De Blasio attributed the sharp drop to the "broken windows" strategy - which emphasises the pursuit of crimes no matter how minor - adopted by Bill Bratton, the police commissioner who retired a week ago. ..
