I just think its very black and white, if you are accused of a crime, a jury decides if you are innocent or guilty. If you are guilty you are sentences accordingly and within the guidelines of the offence and the framework of sentencing. There maybe mitigating factors but even with these they can only have a tiny impact on sentencing as it has to taken into account the punishment rather than the reasoning behind it.
I have been annoyed lots of times in the past of women who have been victims of abuse who then hurt or kill partners getting life sentences, but I suppose you have to be realistic. The law is there to make sure it also stands as warning, that if you commit the crime you will be sentenced accordingly.
But yes, we have all been through this over and over again, I think it perfectly healthy for us all to have differing views. I quite like someone not having the same views as me so I can debate, discuss and sometimes reassess my own views and gain new ways of thinking or opinions.
