text:  Thanks, Colonel. Crime sprees like this terrify the general public and are becoming more common. Many times they are fueled by drugs and alcohol or mental illness, leaving the attacker with little or no self-control. These people tend to continue their crime spree until they're stopped forcibly by police or an armed citizen. The armed citizen in this case performed well, considering his situation. He was facing a violent felon with no qualms about shooting him. Plus, he was also outgunned.
