am I missing a thread on this or has it not been brought up yet?

Not going to post a link to the video until Gene weighs in as to whether it will violate the rules.
There are edited versions of it.

Easy to find if you youtube it.

I'm going to go ahead and weigh in that the shop keeper was not justifiable in his use of deadly force.
He's playing the 'fear for my life' card and maybe he was.
But, the video shows (to me) that no physical threat was ever directed to the shop keeper.
