Clearly it was sufficient. That is not up for debate, is it?I think it was!!!!!I think the adjective you are looking for is "sufficient" reason.Yes, Wilson had a reason, good reason? That's subjective. Good for him maybe.Wilson had a good reason. The thug took it upon himself to act like a thug then paid the price for it.
Since the Grand Jury refused to indict based on lack of evidence, it's very objective.
IMO the debate isn't whether the Cop was justified and/or had sufficient reason. The question is would you have killed him or not and if so why, and if not why. I probably would not have fired my weapon at all against this unarmed dude. When he cursed at me, knowing that I've got backup coming "seconds" away. I would have just hung back in my vehicle take some pictures of the guy strolling merrily down the street. Why start a chase against "two" guys when you have backup coming? See if it looks like he's armed. I'm not gonna let some big dude reach into my window I'd probably roll the window up. Epic foolhardy to try to open your door from a seated position with a big dude on the other side of the door and your window open.. WTH?
So, as a police officer, you would hide in your vehicle instead of doing what was necessary to apprehend the suspect? How long do you think you would remain employed as a cop, and how many other people would you allow to be victimized by the suspect before he is apprehended?
