wrong, wrong, and wrong.
Due process is judicially construed, and wasnt around at our founding. We had rights, but they had yet to be specifically enumerated by our govt. The cons ution did not provide the specific guarantees that encompass due process.
Courts have fleshed it out. you are guaranteed the right to have notice of charges, you are guaranteed the right to have a lawyer if you want one, you are guaranteed the right to have the opportunity to be present if your rights are in jeopardy, you are guaranteed the right to be heard in your own defense. Those things have come to being inside courts throughout the twentieth century.
You are actually on the right track, but you need to do some more investigation...you dont grasp the whole concept here.
