Even if that bartender was "innocent", if HE pointed a gun at me like that...
... after all I wanted to do was check his paperwork while my wife was missing and possibly kidnapped, I would not simply let it go, I would inform the police and possibly making him a suspect and even if he wasn't in on the kidnapping at all, I would harshly tell him off saying...
"Excuse me MR, my WIFE was missing, ALL I wanted to do was see the slips and be convinced she wasn't around and didn't come into a pub that's all, you DON'T point a GUN at people for God's sake for something like that. Say you're sorry!"
And do you think he should've?
And plus, if the bartender really was innocent, why was he so against that man simply checking his slips to determine if his wife really did come into the pub or not? And to point a loaded GUN at him for THAT? God. And even if in his mind Russell did call him a "liar", why does he get so worked up after that?
