Thanks Aftermath for answering my GR Turner example for him. My point is that the 'suggestions' you refer to almost always take the form of excuses or justifications. It is very rare indeed that one of you are ever willing to say `That may have been the smarter option` or `yes, OP did act like an idiot for doing x,y or z'. Instead, with the example I used, we ended up with the suggestion of an armed gang that could have been spread throughout the house and about to launch themselves into an immediate attack on the bedroom, making escape for Reeva impossible (again, that is way, way beyond anything OP conjured up in his fevered imagination). I get the feeling that had he not turned around and changed his plea on the Tasha`s charge one or all of you would be saying that he says he didn`t pull the trigger because in his perception he didn`t or words to that effect.
Pretty sure I said I thought the smarter option would have been to stay in the bedroom and keep the hallway covered. But who said Pistorius is smart? That's the thing-you didn't ask if anyone thought his actions were stupid/rash/ill judged. You asked for reasons why he might have acted the way he did.
