CARL AZUZ, cnn STUDENT NEWS ANCHOR: In the city of Charlotte, North Carolina, a state of emergency. Governor Pat McCrory declared it Wednesday night, the second of violent protest.
What the state of emergency means is that the National Guard and state highway patrol will be deployed to Charlotte, to help local law enforcement.
Yesterday, we reported on the police shooting of Keith Lamont Scott and the violence that followed Tuesday. Demonstrations began again Wednesday.
They started out as peaceful, but that changed overnight. Protesters looted stores, set fires and vandalized cars and buildings.
Police say 44 people were arrested and that nine civilians and five officers were injured. The city of Charlotte said one man was shot by another civilian and was on life support as of last night.
Police used tear gas to break up some of the demonstrations. As far as evidence goes of Scott shooting, the police chief says opened fire after Scott refused to drop his gun. Authorities say they had video of the incident. But while they may allow Scott's family to see it, they do not plan to release it to the public. The police chief says that would be inappropriate.
A spokesman for the Charlotte Fraternal Order of Police says he reviewed the footage and does not believe police did anything wrong. But anger in Charlotte has been fueled partly by protesters who disagree and don't think police have been open and honest about the incident.

Quick update now on another police shooting we reported yesterday. In Tulsa, Oklahoma, a district attorney announced Thursday that Officer Betty Shelby would be charged with first degree manslaughter. Shelby is the policewoman who shot and killed Terence Crutcher last week, next to his car in the road. More details on that incident are available in our show archive.
