pros: If TH angry about what she shes upon entering trailer isn't it going to be directed at JB and AH - not "let me go get a gun" that she probably didn't know was there. And would her anger be directed at AH more or JB more? what's the likelihood of her glancing over and see the gun, perhaps having to get by them to get get especially with JB the cage fighter trying to stop her. Not impossible, but she needs to swing the gun around in a pretty confined area, but if that is what is happening and JB is here and she is a step or 2 away...before its a danger she is going to have to swing it around, yet he sits there like a bump on a log according to him. the gun "happens" to be loaded, safety off, racked and ready to fire. Once there is a shot in confined area, pretty loud blast will get somebody's attention, racking the gun would get someone's attention (talking about Mr. Beebe).
pros: I am going to give JB benefit of the doubt, lets assume Ah is standing up and feuding with TH, lets assume she is back as far as she can be although confrontation presumes people moving towards each other not away. Lets put TH as far back as she can be...still can't explain shot in leg. (JC shows how hard it is to maneuver gun in trailer into position)
pros: not evidence that JB was cowering in the corner. We know gun can jam, but luckily for JB it jammed at precisely the right moment to save his life. In his original statement JB "I acted in self defense, I ain't no murderer, I am a victim"...but then "I though about killing myself, really? really? you almost became a victim and saved yourself by firing a gunshot to the head of someone else, and now you are thinking about killing yourself...WHY?"
