From the Washington Post:
Calvin Kyle, 26, had been pulled over, handcuffed and put in a police cruiser after he was seen riding a stolen motorcycle near County Road and Marlboro Pike in District Heights, law enforcement officials said. But as District Heights Police Sgt. Johnnie Riley attended to other matters, Kyle got out of the cruiser and began to run, said the officials, who spoke on the condition of anonymity to discuss the ongoing investigation. … Family members said that they had been told that Kyle was in and out of consciousness and had no feeling in his legs. It was unclear, they said, if he would walk again, though it appeared he would survive.
Of all the aspects of police training, the one thing that ought be crystal clear is the circumstances in which deadly force is justified. This does not seem like a close call.
