Very sad situation.

I suspect the decedent had had a few celebrating the basketball victory. That was what he was there for.

Did that impact his judgement, leading him to get involved in trying to break up a fight and then to ignor the cops’ command to leave his gun on the ground? I’ll bet it did.

To me, the takeaways are: no booze when carrying a gun, stay out of other peoples’ dispute and DO WHAT THE COPS TELL YOU TO DO IMMEDIATELY!!
