There are three types of lies -
1) Lies
2) Damn Lies
3) Statistics
Numbers means nothing if not provided in full context.
The word "unarmed" is misleading.
As a police officer of over a decade I have come close to shooting an unarmed person. In my story, the suspect had a felony warrant for aggravated assault. We Identified ourselves as police and the suspect ran. We chased him into his ex-wife's house and into a small room just inside the entry way.
Once inside he kicked my partner, threw a loose interior door at him and then grabbed my partner's gun. Fortunately for the suspect, I subdued him before he could gain control over the weapon. The suspect went to jail and eventually pleaded guilty to all charges. Everyone else went home safe.
Unarmed does not mean incapable of causing serious bodily injury or death. It just means a person is not in immediate possession of a device which is specifically designed to cause injury or death.
Can you pick up an object and bash a person's head in causing death?
Can you kick a person in the head so hard it causes serious bodily injury or death?
Can you choke someone to the point of causing serious bodily injury or death?
Can you ram a person's head into the pavement until you cause serious bodily injury or death?
etc.
What I tire of is a society that wants immediate action and results. Everyone gets due process, but police officers. A grainy cell phone video showing only a part of an incident played non-stop on social media and big 24/7 cable news networks is all that is needed to convict a police officer. Everyone else is givev the right to a full investigations, due process in a court of law, and the presumption of innocence until proven guilty beyond a reasonable doubt.
