If you read the investigative news article that the Register Guard published on deconstructing this shooting, you would know that there were no other witnesses to the shooting, other than the police marksman.   And that no video of any kind was recorded that showed the shooting, or what the police officer saw.

There is no way to know if Babb really pointed the rifle, or if the officer mistakenly thought that he was pointing the rifle at him.  

The article also points out that Babb's hunting rifle was not loaded.   He had retrieved the rifle, but had failed to get any ammunition for it.

You should take the time to read that article.   Babb's VA counselor, who was initially on the phone with him during the incident, is highly critical of the Eugene Police.   Her testimony in court could potentially be very damning to the city.
