Shooting someone in the back who might or might not be attempting to locate a weapon seems a pretty low threshold for executing them, even if they are ignoring your orders. I don't know about prior convictions, didn't see a mention of them on any news articles or the police statements they gave after. Sure it's not just some claim you read on social media? From witnesses it sounds like he was trying to break up a domestic fight with his family all there, so it seems unlikely he was planning to start shooting at police
{edit} so he has some pending charges for domestic, but no weapons charges

I did put the caveat that my reading was on the video alone, you seem to be quite well informed on the background, and they are good sources
I guess they'll find out in the enquiry, if he didn't end up having a gun in the car they'll be in hot water
