Data collected by the Washington Post newspaper suggests that the number of people shot by US police is twice as high as official figures claim. The paper said that during the first five months of this year, 385 people – more than two a day – were killed. The number of black people was disproportionately high among the victims, especially unarmed ones. Official statistics rely on self-reported figures from law enforcement agencies. They suggest about 400 people have been killed each year since 2008. The US has seen a number of controversial cases where unarmed black people have been killed by white police officers.
