Not surprised by the sentence, but this should have been longer. Oscar Grant was killed by a BART police officer in San Francisco. At the time he was shot, he was on the ground and in handcuffs (if I recall correctly, it is possible that he was face down on the ground hands behind his back but not yet handcuffed). Numerous videos of the incident make it clear that Mr. Grant was not a threat and was in fact compliant.
The defense claims that he accidentally shot Grant, confusing his handgun for a taser. I’ve never handled a handgun or a taser, so I’m not one to speak on whether or not you could actually confuse one for the other. But there was simply no reason to use either weapon on Mr. Grant under the circumstances. A topic for another time, is the effect of “non-lethal” tasers on police behavior. I’m inclined to think that instances like this where an officer uses (or attempts to use) a taser, even though such force is completely unnecessary is somewhat common.
I’ll add one take on the situation from an author that I really like. One of his best friends (unarmed) was killed in his driveway in front of his child by Maryland police officer, so his negative view of the current police state is somewhat personal. With that bias in mind, I always enjoy reading his thoughts on the subject.
