Everyone is entitled to justice, and to fair treatment before the law. This especially includes people in prison who are totally dependent on state control and the most vulnerable, subject to the harshest punishment available. However prisoners are often unable to exercise those legal rights, isolated from support, in cells without resources, but with time and incentive to defend themselves.
People in prisons must have the ability to access resources that assist preparing their defence, and exercising their right to a fair trial. This is why it is essential for people in prisons to have access to computers, as a tool to access evidence, a source of legal knowledge and the ability to present information to help themselves. That right is supported by many cases. The courts can adjourn and release to bail.
