9. No Unfair Detainment. Nobody has the right to put us in prison without good reason and keep us there, or to send us away from our country. 

At the time the Universal Declaration of Human Rights was written, the realities of World War II were just coming to light.  The detainment (and murder) of the Jews, Roma and others in Europe, the massive relocation camps in Asia and the Japanese interment camps in America - these were shocking on a level unseen historically.  No government, no persons have the right to detain people with just cause and reason.
