Obviously there are other possibilities for his supposed refusal to let go of the knife, namely that he was most likely in grievous pain and quite possibly too disoriented at that point to comply with such a demand.
It doesn't really matter, because it's not like this is a situation where they are going to give Sammy the benefit of the doubt.
Back to the hypothetical scenario I mentioned, since you didn't actually answer the question I posed. Do you believe a person who on the ground and clearly incapacitated is still a threat?
It's not a question that can be answered hypothetically. It would depend on the exact situation and the perception of the officer in question at the time. And your definition of "incapacitated" may be different than mine.
But I'll throw you a bone anyway. If the suspect was no longer in possession of a weapon, and appeared to be incapacitated to the point that I could be reasonably sure that I could put him into custody (cuff him), then I would see no reason to employ lethal force to do so.
How about a individual, armed only with a knife who has been felled and is now recoiling in pain after being shot? What is the threat level of such an individual even if he is still considered to be in possession of the knife and the nearest officer is some 20 feet away?
How many examples of wounded suspects killing or injuring people in that same scenario (with
only a knife) do you need to understand that you simply don't take chances. You keep forgetting that Sammy's well being is the absolute lowest priority here.
Only a knife????
And it would seem as though Ontario’s ombudsman agrees, for they most certainly would not be moving towards an investigation into to how police are trained in dealing with potentially violent situations if there wasn't some concerns about whether or not the use of lethal force under these circumstances was appropriate.
Neither you or I are qualified to make such an assessment.
There are a lot of things everyone has to wait for before any of these questions can be answered.
But I will tell you one thing...the cops were there to do their jobs that night. It doesn't matter whether you think they did a good, bad or just average job on that particular night...they were there because Sammy forced them to be there. Confronting police in a irrational, dangerous and threatening manner with a deadly weapon, and not putting it down when asked to do so comes with serious consequences. One very likely one is that you are going to be shot and killed.
Despite what you may have heard, there is no after life...this is the only life we have. And Sammy pissed his away that night. You can't blame the cop who was there just trying to his job, and may or may not have done the best job he could have that night.
