The law is BS.
The law is implemented, interpreted and practised by incompetent men. The law is manipulated by the rich and powerful. That is no law, that is BS. This is why we need Shariah, but even more so, we would need educated, capable, men of conviction to implement it. Where will we get those from?
The man is ill - so what? Do prisons not have hospitals? Could the hospital not be temporarily upgraded? What about those who are ill and too poor to afford an army of lawyers? Is the law equal for them?
