I am not an open carry person for that reason, but I can certainly understand "the conversation turned to his new gun". How many times have we all talked about our latest acquisition, although generally not with strangers?
He IS open-carrying it. As such, it might (unsurprisingly) become a potential topic of conversation.
Quite frankly, the discussion (even with a stranger) doesn't surprise me. After all, we give kudos to MissMichelle when she engages a stranger in intelligent firearms conversation, right? Putting a normal human face on gun owners?
To my mind, the problem we have here has to do with the victim failing to stay away from the three Ss. (Don't do stupid things with stupid people in stupid places. Technically there is a fourth S which is "...at stupid times.")
2:10am, folks.
Tell me, do---how many of you hang out on the streets talking with anyone who walks by at 2am?
Situational awareness fail, yes--mostly because anyone walking around
at that time of night who just walks up to you to talk is someone who should be viewed with a significant amount of reserve.
2pm at the Old Cheney Farmer's Market, in the midst of a crowd? Sure. 2am on the street with no one else around, and no reason for that person to strike up a conversation? Yeah, that should have been a potential threat indicator.
