Being accused of a crime is a life-changing event. The most important thing to remember is that your guilt has not yet been established. You are presumed innocent until proven guilty beyond a reasonable doubt at trial. That’s the way the system works. You are innocent unless and until a jury finds you guilty. Along with the fundamental presumption of innocence, there are a number of specific rights provided by the U.S. Constitution—mainly through the Fifth and Sixth Amendments—that protect a defendant throughout the criminal process.
