Rich or poor....

Outrage at the news that a man who won several million pounds on the National Lottery has been granted Legal Aid to defend a criminal prosecution. But why? Our legal system works on the principle of the presumption of innocence (doesn't it?), so why should an innocent man have to dig into his own pocket, however deep it may or may not be, just because an accusation is made against him? If he's found guilty, that's a different matter, but until such time, he should be entitled to look to the State for assistance with his defence costs, and his personal financial position shouldn't come into it.
