So now coming out he was a refugee immigrant from Uganda who the US tried to deport twice for convictions related to trafficking cocaine and felon in possession of a firearm and misc other charges. Uganda wouldnt take him back so they let him out of detention and released him back onto our streets where his behavior caused this confrontation.
As to the shooting, someone reaches into their pocket and pulls something out and takes that stand pointing what might be a weapon at me and I'm shooting too. This is about as justifiable as it gets without taking incoming fire first. I do think police sometimes escalate to violence too quickly, but this is unquestionably a good shoot.
