I think if the suspect is actually bringing deadly force to bear on a person, or is driving in a way that undeniably presents a real danger to others using the roads and walkways, then deadly force is appropriate to stop the threat.
If, however, the suspect is leaving in a direction not immediately threatening anyone, and the path and speed of travel are not causing imminent danger to others, the police should use discretion as to whether the situation really rises to the level of a lethal threat.
Non-compliance with law enforcement is not supposed to be a capital offense. Seems like this has been changing lately.
The legal standard for assessing a threat used to be what a reasonable person would think or believe. Now it seems police take a leap from non-compliance to "the suspect was aggressively threatening." I think the reasonable man left for a long vacation. Placing oneself in danger by stepping in front of a car should not give the police justification for homicide. The COP can step out of the car's path just as easily. It's becoming "stop or I'll shoot" for any infraction, where failure to stop then becomes the overriding violation.
