Question: can u be tried for the same crime twice

Answer: No, Double jeopardy is a procedural defence that prevents an accused person from being tried again on the same (or similar) charges and on the same facts, following a valid acquittal or conviction. As described by the U.S. Supreme Court in its unanimous decision one of its earliest cases dealing with double jeopardy, ``the prohibition is not against being twice punished, but against being twice put in jeopardy; and the accused, whether convicted or acquitted, is equally put in jeopardy at the first trial.''
