My thoughts exactly. No blood spatter from a lethal neck wound is the key because a carotid artery or any other neck vessel spurts with every heartbeat. Her blood would have covered the doors, the floor and the bystanders. The blood slowly oozing from her nose is not consistent with a gunshot to the neck either. I couldn’t tell the caliber of the handgun but probably a .38 or .45. Either way, her neck would have been gaping open. There isn’t even a flesh wound.
How do you know the exact bullet entry point?
If she had been gut shot or lung shot by either of those calibers— center body mass with what the Capitol Police use, which are spreading framentary safety rounds— the damage and blood/tissue exit wound would have been very large and large amounts of tissue on the window aperture to her right and all over the wall behind her on the right. None seen.
Also noted- the muzzle flash of what looks to be a Glock 17 or 19— is not very large. Real proof is— burial notice for Babbitt, obituary or some record of the dispensation of the body, if it happened.
A good comparison for some of these shootings is the aftermath of the Charlie Hebdo shooting in Paris:
