Arizona police officer kills man.

My maximum likelihood estimate is that this shooting was not necessary.  The officer was not alone.  My view is that the man could have been cuffed while lying on the ground by other officers and that the orders to follow detailed somewhat confusing instructions would have been difficult to follow exactly under the circumstances.  It was clear from the beginning that the man had trouble following the officer's orders.  I do not see anything that suggests the officer intended to create a situation that would enable him to shoot.  Rather, I see poor judgement about how to handle the situation that led to a perception of heightened risk when the man's hands were lowered to the vicinity of his waist while attempting to crawl.
