No person shall be subject for the same offense to be twice put in jeopardy of life or liberty; nor shall he be compelled in any criminal case to be a witness against himself; and the failure of the accused to testify shall not be commented upon nor taken against him. In all criminal prosecutions, the accused shall have the right to a speedy and public trial, to be informed of the nature and the cause of the accusation and to have a copy thereof; to be confronted with the witnesses against him, to have compulsory process for obtaining witnesses in his favor, and to have the assistance of counsel for his defence. Every man is presumed innocent until he is pronounced guilty by law, and no act of severity which is not reasonably necessary to secure the arrest of an accused person shall be permitted. All persons shall be bailable by sufficient sureties except where the judicial authorities shall determine that the presumption is great that an infamous crime, which term shall include murder and rape, has been committed and that the granting of bail would constitute a danger to the community. Bail shall be set by such judicial authorities. Excessive bail shall not be required, nor excessive fines imposed nor cruel or unusual punishments inflicted.
