I'm on Team Tonka. It's definitely manslaughter. From Wikipedia (sorry -- it was quick though):But we dont know the moment the decision was made. When the door is opening? Sure thats a snap decision, but how about when he parks his cruiser. Now he makes that decision, and he has the time while turning off the motor, getting out of the car, meeting with the other cops (who never fired a shot) deciding which door to pound on.... Clearly time to reconsider or at least reign in your emotions.
"Voluntary manslaughter occurs when a person intentionally kills another person after "adequate provocation"; that is, there has been action that was sufficient to incite an "ordinary person" to "sudden and intense passion" such that s/he loses self control. It should be noted that the time between provocation and the killing should not be long enough for the passion to have cooled off.
Involuntary manslaughter generally occurs in only two cases. The first is when someone is killed due to criminal negligence, and the second is when someone is killed during the commission of another crime, where the intent was not to cause bodily injury or death.(This is often called "misdemeanor manslaughter".)
Murder is the act of killing another human being with "malice aforethought". Malice aforethought is defined to be the intent to kill or to inflict bodily injury, either express or implied. If a deadly weapon is used, intent to kill will necessarily be implied by a court of law."
