A police officer responds to a call about a young person with a gun sitting on a park bench. Upon arriving at the park in his cruiser, the officer tells him three times to “show your hands.” The young person did not show his hands and may have reached toward his belt. Within two seconds of arriving, he was shot and killed by the police officer. The young person turns out to be 12 years old and the gun turns out to be a toy. Is this a justifiable use of force by the officer? Explain your answer.
