As far as innocent until proven guilty that is not always the case say me and you are arrested for a crime we both did not commit I have money and you do not so I make bail and hire a great lawyer and I beat the charge but you can't afford that now you have to sit in jail and fight your case from behind bars months go by and you start to miss your family the courts offer you a plea deal you can go home right now but you have to plead guilty to a lesser charge most people take the plea deal now you have a criminal record for something you didn't do
