President Obama has said he's deeply disturbed by video footage showing the death of a 17-year-old black man who was shot 16 times by policeman in Chicago just over a year ago. The footage was released on Tuesday after prosecutors announced that they had brought murder charges against the white police officer, Jason Van Dyke.
A court in the United States has convicted a man of murder after he shot dead his wife and posted a picture of her body on Facebook. The jury in Florida rejected Derek Medina's argument that he had acted in self-defence. The court was told that he had written on the social media site that he expected to go to prison or be sentenced to death for the killing.
