rhino, I have no particular feelings or opinion about him, so no, I don't 'just want to believe' he's innocent because I like him.
As for the fair hearing thing, I think there has already been a lot of knee-jerk reaction around this case and yes, I think he has possibly started from a point of being believed guilty.
I do not know if he's guilty or innocent at the moment but I believe in minimal sensationalism and innuendo and in innocent until proven guilty.
'did he really think it was someone trying to get into his house.' Well, perhaps he did.
'Why would an intruder lock themselves in a bathroom?' I don't know. Maybe in the cold light of day he doesn't know, but if you were scared out of your wits in the middle of the night you might think differently.
'Why did he say he was asleep when 2 witnesses heard screaming between 2 and 3am (not confirmed)' As you say yourself, it's not confirmed.
'would he seriously not have woken Reeva? or her not have woken herself when he got out of bed to go to the bathroom and shoot?' See my answer to the 'bathroom' point.
Don't get me wrong, if it becomes clear that he did knowingly murder his girlfriend I will condemn him as heavily as anyone else. Until then I'm keeping an open mind. I only hope the judge is too.
