You asked what tactics we currently use (more specifically how Officer Gummer would respond) and then you insult me. Fair trade I guess, no wait that's not.
If YOU went to a call with a subject with a rifle and you approached without any weapon at the ready or at least unholstered, you would be at the mercy of the unknown person with a rifle, hoping you can draw and return fire before he empties a magazing into your torso, shredding your body and killing you. Here is a feel good video you would view in the police academy-

You train on approaching an armed subject with superior firepower, numbers, and tactics. Will luck on your side, you may not get killed. Have you ever served in the military or seen people shot or otherwise killed up close?
If you are telling me that I approach a situation with an armed subject with superior firepower and my rifle ready, and you disagree with my position, I dare say you have little or no tactical training or experience. And yes my training and patrol experience is only in Austin. I am assuming you think negatively of my department.
You qualify your critique of an experienced police officer by stating you heard STORIES from your father who was an LEO. My experience is from 7 years as an airborne infantryman and leader, plus the last 10 years as a patrol officer, street supervisor, and detective in my department.
Your opinion is duly noted and hopefully I have shed some light on proper tactics when facing an armed threat.
In case you did not notice, several law enforcement PRACTITIONERS have chimed in. Maybe if you don't trust a veteran soldier and police officer with nearly two decades of tactical and combat experience you will listen to others.
But this is the internet where everybody knows somebody elses job better than they do.
That video is not even relevant to the discussion, that is not the same as an individual walking down the street in downtown anywhere with. Rifle slung on his shoulder. The problem seems to be, you and several others, want to treat both incidents the same. And that is what is so disturbing to some of us.
