Not to bash on you....but don't be lazy, there is a lot of info out there on the web on this particular shooting. The individual shot (John T Williams) was carrying a piece of wood and was a known Native American wood carver. He was also known to be a bit of a drunkard and by the sounds of it was living in an assisted living type scenario, and had previous substance abuse issues. Alse those who knew him stated that he was deaf in at least one ear and was very hard of hearing.
I try very hard to give officers the benefit of the doubt, but this situation appears to be one of a rash action by the officer and an outright execution. Viewing the video you can see him jump out of the car, hear him chase the guy down and rattle off three "heys" and then rattle off "drop the knife" very rapidly without much time for comprehension, especially puting yourslef in the shoes of someone hard of hearing that may have been under the influence, followed by the shots. Judging by the news reports this officer will get off without much of a discipline. Whether it's lack of training or what, this man paid with his life. The rather unfortunate part is that particular people will try to discount the victim or devaluate his life simply because of his mental/economic situation. To me this makes the situation even sadder.
In regards to the incident itself..what was the cause for stopping the man? Was there a complaint or was this a situation where the cop was pissed off already and wanted to "make somebodies day" and this poor fellow happened to j-walk in front of his cruiser while whittling a piece of wood? Whatever it is I don't honestly feel justice will be served equally as if you or I acted this irrationally.
