“Bail has only one purpose - to ensure that a person accused of a crime will appear in court for his trial. We presume a person to be innocent until he is proven guilty, and thus the purpose of bail is not punishment. It is not harassment. It is not to put people in jail. It is simply to guarantee appearance in court. This is a legitimate purpose for a system of justice. In practice, though, bail has become a vehicle for systematic injustice. Every year in this country, thousands of persons are kept in jail for weeks and even months following arrest. They are not yet proven guilty. They may be no more likely to flee than you or I. But, nonetheless, most of them must stay in jail because, to be blunt, they cannot afford to pay for their freedom.”
