Can AI support systems be used in criminal trials?

Proposals to use AI in criminal trials cover different roles, from searching precedents and organizing records to recommending sentences or assessing risk. These uses differ in how well defendants can examine and challenge the result, and in the consequences of errors. The question does not claim that a particular system currently replaces a court. It asks how much assistance should be allowed when reasons must be explainable, bias must be checked and a person must retain final responsibility.
