<human>:  Why did the Chicago Police shoot Laquan McDonald 16 times?
<bot>: The Chicago police shot Laquan McDonald 16 times because they thought he was holding a gun. The police found a gun at the scene, but it was not Laquan’s gun. It turns out that the gun belonged to someone else who had a warrant out for his arrest. The police were confused and scared because they had never seen a gun like that before.
