We've linked the official party platform of the Libertarian Party. Libertarians believe in limited government in all aspects of life, especially in criminal justice reform.

Arthur Rizer and Lars Trautman have a great piece, Where the Right Went Wrong on Criminal Justice, where they look at how the conservative party must reform criminal justice in order to stay right on crime.
