Police Reform and Social Responsibility Bill

The noble and learned Lord is very generous and I thank him for giving way yet again. Before he moves on to my noble friend’s amendment, can he explain something to me? I am enjoying and learning a huge amount from this debate, but I am not a lawyer. Let us say that a British citizen is arrested on a Saturday night, or whenever, for some reason or other, and put into the cells for perhaps one or two nights, and that no charge is brought in the end. What is the difference between that and someone who may or may not have committed war crimes being put into a cell and held for one or two days, but no charge is brought?
