Although the officers should be cautious, they should also look at the entire situation before deciding to shoot to kill. The man rolled over several times, so he was likely disoriented with a possible concussion. Apparently he was shot near his vehicle, so it is unlikely he made a charge toward the officers. The TV report stated many shots were fired and the vehicle was riddled with bullets. The statement that the officers felt threatened that he had a weapon did not make sense to me. And we have heard no report that a weapon was found.
To me, this is not a situation to be trigger happy, and now his wife, children, father, mother, siblings, and the entire community has to live with the loss of this wonderful person.
It is entirely possible that this man was grieving the suicide of his younger brother only 3 months ago and perhaps lost control of his emotions. He may have endangered lives with such high speeds, but he didn't deserve to be murdered.
Traveling at such high speeds at 2:30 in the morning - is he drunk? If so, are drunks a threat to shoot anyone? Is he trying to escape a scene of a crime? Not likely at 2:30 in the morning. All I'm saying is looking at the situation as a whole, the officers should recognize that there is no significant threat on the officers life!
We now must mourn for this loss. But it is also hoped that justice be served and that lessons are learned for the next situation to avoid such horrible consequences.
