A contract killing is carried out by two individuals on a motorbike in dense urban traffic at approximately 9 PM. Three shots are fired through the driver's window at close range. The attackers do not stop, do not search the vehicle, and do not take any possessions. They disappear into a network of unpaved side streets. No CCTV captures the attack. Based on behavioral analysis of the attack methodology, identify three specific operational characteristics that distinguish this as a planned contract killing rather than a spontaneous act of violence, and explain what each characteristic reveals about the level of planning involved.
