Even though this is a very old TV series, it still has a slip up. We were watching an episode with Nick Barkley confronting an old friend of stealing gold. The friend pulls a gun, and Nick walks away saying he's going to turn him in. the friend pulls a gun saying he'll shoot. Nick continues walking the friend still insists he's going to shoot. He does and hits Nick in the right shoulder. As Nick is lying on the ground

the friend wants to shoot him but can't do it.

So he takes his handkerchief, and is stopping the bleeding and it's very obvious it's his right arm. At the end of the show Nick is in his living room with his arm in a sling it's the left arm. I think things like that should be checked. Make sure which arm is injured.
