I haven't been following the Pistorius trial very closely (hardly at all), but is it just me or are the media getting somewhat mixed up by the fact that he appears to be trying to argue, in two completely different ways, that there was not the necessary intent to be convicted of murder? ("I fired the gun accidentally" [no intent] and "I intentionally fired the gun mistakenly believing that there was an intruder behind the door" [putative/mistaken self-defence]).
The fact that the media seem to be quite confused by it indicates how it might work as a trial strategy in front of a jury, but it is hardly going to wash in front of the Honourable judge.
Consider this from the BBC's Andrew Harding: "He knows that he could be cleared of deliberately killing Reeva Steenkamp, but still be found guilty of intentionally murdering "someone" behind a closed door."
That's not right at all, and Harding is mixing up transferred intent and the victim. There aren't two murder charges - if without a lawful defence he deliberately fired at "someone" through a closed door that resulted in the death of Reeva Steenkamp then he is guilty of the murder of Reeva Steenkamp.
