Think of a time when something traumatic’s happened to you. Did you clearly remember every detail? Would you appear convincing under aggressive crossexamination a year later? Now imagine that the traumatic thing was accidentally/negligently killing your girlfriend. Fair to say that’d mess up your day.
Lots of folks on here seem keen to make black and white judgements, “his story is inconsistent- he must be guilty” There’s lots of reasons his story could be inconsistent or inaccurate, not wanting to face up to the facts doesn’t mean he murdered her.
Also I think it’s pretty hard to really put yourself in his place- mate of mine grew up in south africa, he’s more understanding of the “**** someone’s in the house, shoot them before they shoot you” approach than I am. And no denying he’s more vulnerable than an able bodied person so maybe reaching for a gun becomes more reasonable, and the level of fear/panic/paranoia required to pull teh trigger on someone you’ve not seen becomes less insane.
The stuff about his dodgy firearms history has been pitched as an attack on him but to me it seems to back up the accidental death defence- he likes playing with guns, that’s consistent with being too quick to use one in “defence”
Seems pretty certain he’s guilty of being an arsehole and a danger to others. Not sure he’s a murderer. I’d be more suspicious if he had a perfectly rehearsed tidy story with no weaknesses- and really, does this strike anyone as a good way to murder someone? Having said that he’s an arsehole, so maybe it did.
