Correct. Miranda warnings, or "rights" only apply when someone has been placed under arrest. Prior to that, conversations with LE are voluntary. Whatever you say is what you said.

How the "use of force" issue pans out in this case will depend on the officers ability to articulate the facts. It sounds like their collective story is that he pulled a gun. Use of force, deadly at that, is justified in such an instance. Not required of course, but it has been deemed "reasonable" through past case law (graham v connor, tennessee v connor, etc.)

I am glad he didn't die. I am glad the officers didn't pump him full of lead and make sure he didn't live to take another breath. Is that what he deserved. Probably. I am glad that the responding officers showed the restraint and used force to eliminate a threat rather than fulfill some personal and moral agenda. It seems as though they put their professional duty ahead of other factors and acted in a manner appropriate for a person who has sworn an oath to protect and serve the people of this country.

As with many professions, I get the idea that a few paint a large part of the picture for the majority in the LE field, in the eyes of the public at least. My hats off to those that choose this as a career and give of themselves to help us all live a little safer life.
