No person shall be held to answer for a criminal offense without due process of law, and no person shall be put twice in jeopardy of punishment for the same offense, nor be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty or property without due process of law. All persons before conviction shall be bailable by sufficient sureties, except for capital offenses when the proof is evident or the presumption great. The privilege of the writ of habeas corpus shall not be suspended unless the public safety requires it in case of rebellion or invasion.
