Not saying they made a mistake at all. What a horrible scene for them to have come into. These officers deserve our utmost concern and prayers for what they experienced and continue to experience.
That being said, if I recall, the log also stated that James answered the door, and he couldn't, as he was deceased. Not seeing the crime scene photos and positioning of his body, we have to go by whatever eyewitness accounts we get.
Not trying to argue with you here, just working on getting my facts straight, thanks for working with me on this.
