Introduction
Deadly force has been statutorily defined as that force:
". . . which is likely to cause death or great bodily harm and includes, but is not limited to: (a) the firing of a firearm in the direction of the person to be arrested, even though no intent exists to kill or inflict bodily harm, and (b) the firing of a firearm at a vehicle in which the person to be arrested is riding."

When feasible, some warning is given. However, police cannot use deadly force to make an unlawful arrest.

For example, a police car ramming a fleeing vehicle can obviously cause it to crash and kill the occupants (or innocent bystanders). One technique for halting a fleeing vehicle is called "precision immobilization" and is used by some law enforcement agencies (Pearson, 1992). While theoretically, such a tactic may be sound, fleeing criminals often do not obey the rules of the road.
The U.S. Supreme Court has reviewed a procedure that is known as the "dead man's roadblock." This occurs when the police on the roadway intentionally erect a roadblock so that the fleeing person's observation of the impasse is restricted until it is unlikely that he or she.........
