Unless you consider the bag a weapon I think we both agree he was unarmed.
Firstly, my previous comment was about emptying a mag, he fired 4 round, not the same, but I hear your point. Second, I don't want to state is as fact because I don't remember, but I think someone mentioned him having a fire extinguisher on him. Additionally, one of the witnesses today, testified to this individual throwing a bootleg chemical bomb at her while she was with Kyle. I do not know if he would be considered armed legally, but that doesn't mean he was/wasn't a threat.
You are the go to person for that. I seen reports the 4 shots were less than a second. Is that what witnesses said?
I believe one of the witnesses today mentioned the time frame. I'm trying to find some video, but most of it has been clipped to fit a narrative
