In my opinion the only thing established about Paddock was that his body was dead in the room. The top half you can see a lot of blood at his chest. but they don’t show his right hand or abdomen. Note: No or very little blood on the revolver claimed he used to kill himself.
I would not expect much blood on a revolver used in a suicide with the muzzle in the mouth. The back of the head is blown out; the revolver recoils away from that and, depending on how it was held, the position of the arm or arms, and the original position of the body, usually falls to rest on or a little ways a way from the body. In 7% of the cases, it comes to rest more than a 30 cm from the body, just as shown in the photos.
24% of the time, it stays in the hand.

You didn’t see blood?
I would also like to point out the hand gun that no one seems to have noticed. Top right hand side of image.
There are two photos of him that is it. When he is on the ground dead. The head shot shows a lot of blood on his chest.
Notice there is a drop of blood moving down his chest as though was sitting or standing when the chest wound happened. Some of that chest blood didn't likely come from the head. The drop of blood is on the inside of his shirt seeping out.
The chest wound is a separate wound from the head. It could have been a result of the kick from the revolver. The only way for that to take place is if he was setting or kneeling bending his head down over the weapon before it fired. I don't see a chair right next to him in the pictures. If he was kneeling his legs wouldn't be straight.
None of that makes sense because his legs are straight. Thus he was laying on the ground when the weapon went off for the head wound.
The chest wound is likely unrelated to the head and happened shortly before the head wound.
