Wow. There are several lessons to be learned here for both sides.
Sounds to me that both homeowners, husband and wife did everything right. They notified everyone who needed to know the situation. They stayed on the phone with 911.
The officers going in the house made mistakes, they did not announce there presence in the house according to the reports which would have given the homeowner a chance to posture in a way to keep something like this from happening. Did the dispatcher relay the info prior to them arriving on scene?
I had a incident here in Meridian where my wife called 911 for what we thought someone had broken into the back yard, I didn't tell her to tell them I had a gun out and drawn around the front of the house and I realized this so when I was out front and saw the LEO pull up I put the gun back in the house in a manner that he didn't see it. That is what I meant by "posture". Together my wife and I have fixed this and now know what to say to 911 and do in that situation regardless of where we are at the time. This can happen anywhere, not just in the house. I didn't have the same situation but I know that if I was standing out front with a gun, regardless if the LEO knew there was a gun out of not, it could have went bad.
In this gentleman's situation it may have been tough to lay down the gun in a safe place, certainly if he didn't know LEO were in the house. His wife and lawyer stated it would have been hard to see the gun from that vantage point of the LEO, shot in the back says it all.
I am not defending the LEO, but they have a damn tough job, and made a huge almost deadly mistake. Every time they are on duty, they have to remember to not violate our rights, that is not easy when you throw in the stress factor. As widescreen said, some of us have never had to deal with that stress the officers did. Again, not defending them, I can only hope the department figures out how to fix this for the next time they find themselves in this same situation. I hope the Dept. does the right thing and doesn't cover anything up and hadles it properly. They already cleared the officer based on the video report.
Widescreen said it well, we review this from what we know so far, watch the development of this and learn from it.
