I'm perplexed by the lack of a scope. I honestly think it was a machismo move. Wanted to try n headshot him with iron sights so people would talk about it or whatever. Maybe it was all he had, but I doubt it. There are articles saying he was a member at a local range and practiced there all the time. I'm sure he owned a scope. Maybe he didn't think he'd have time to line up a shot with a scope? Idk, it was just weird.
